This is all news to me! :unsure: All I was aware of was KH3 on PS3 (to which I somehow doubt Square Enix would suddenly throw a paddy and move over to the Wii). Still, this is good news to hear! 
A multiplayer KH sounds wickid and as you guys already said, Wi-Fi linkup would be even better! 
Anything online anywhere regarding these new KH spinoffs? Vids, previews...anything? Will be greatly appreciated! 
There aren't any trailers for it out as far as I know, only trailer summaries and information about them.
KINGDOM HEARTS: BIRTH BY SLEEP (PSP)
Story & InformationThe legendary Keyblade is said to hold phenomenal power.
Some legends say that long ago, its wielder saved the world, while some say that he brought chaos and ruin upon it.
(Ansem Report 8)
Before Sora gained the Keyblade, there were many "Keyblade Masters" in the world.
One of those Masters, Master Xehanort, and his only disciple suddenly disappears, an omen of the great disaster that would subsequently erupt.
And as soon as one Master realises this, he tells his three disciples that they must track down Master Xehanort at all costs...
This is a story of awakening, one which connects to the grand beginning of the Kingdom Hearts story.
The PSP's high-level graphics ability is taken to its very limits.
A new set of three protagonists compose three different scenarios.
The controls, system and graphics follow those of the series so far, while at the same time bringing a whole new feeling to the system!
Directed by Tetsuya Nomura & Tomohiro Hasegawa
Trailer SummaryVideo begins by showing scenes of the ending of "Kingdom Hearts 1", Soon the text "Deep Past" comes up, to be followed by "Shut-Eyes gives birth to the concealed fate"
Scene cuts to an area featuring the boy who looks like Roxas, Ven, talking to a young male with black hair, the area seeming to be like "Hollow Bastion". The boy soon calls the young male "Ven."

The scene then changes to Terra fighting against the mysterious dark male, who looks like he's in a bicycle suit, also from the secret ending. Terra manages to knock off the helmet, but his face isn't shown.
The scene soon moves to King Mickey summoning his Keyblade. Soon the scene begins to change rapidly, and Terra is at a beach, watching two boys playing before resting his sword into the grove. The two boys soon begin to become more visible, and it looks like Sora and Riku playing at the beach.
Finally, Terra says..
"Please don't depend on me, just erase me...friend"
KINGDOM HEARTS 358/2 DAYS (Nintendo DS)
Story & InformationTwilight Town.
As always, Roxas and Axel are watching the sun from the clock tower.

And at the end of that mission, they always meet up at that clock tower, eat ice-cream together and chat about the day's missions.
"Do you know why the evening sun is red? It's because light has lots of colours, and of all of those, red reaches us from the furthest away."
"What're you getting all proud about, Axel?"

This is the untold story of Roxas's time in Organization XIII...

Trailer summaryThe trailer starts from the scene where re:COM ended, afterwards the words "The other side attached to Sora still sleeps" and "The mind comes back whenever they touch." The scene then moves to Twilight Town, where Roxas, and Axel are sitting on the edge, as seen in KH2FM+.
Soon the trailer switches to Roxas being invited to the Organization XIII, and introduced to them, which soon cuts out to another scene of Roxas joining the Organization for the first time. Soon the scene then switches to the King talking about Axel, and Saix with Roxas pulling out his keyblade, moving into gameplay.
The gameplay features Roxas fighting with other Organization Members in a multiplayer game. This one confirms the allowance of being able to play as Roxas, Axel, Saix and Xigbar.
The scene then switches to Xemnas talking towards other Organization members. Xemnas explains that a 14th member has joined the Organization, and the 14th member appears to be a female, wearing a black hood. Soon the title comes up as "Kingdom Hearts 358/2 Days"

KINGDOM HEARTS: CODED (Mobile)
Story & InformationThis story revolves around a single fragment of Jiminy Cricket's "Jiminy Memo".
Following the events of "Kingdom Hearts II", Jiminy returns to Disney Castle. Jiminy has been reading his memo along the way, and a single page makes him stop in his tracks.
This page contains a mysterious message:
"We have to go back, to heal their pain."
But no matter how much he racks his brains, he can't remember what the page is referring to.
The King turns the Jiminy into data, and begin to investigate. And in a world traced by the Jiminy Memo, the Destiny Islands, a sleeping boy awakens.
Thus Sora's new adventure in the Data World begins.
An unlimited range of Disney worlds, distributed to your mobile phone.
An adventure spanning across many diverse, rich Disney worlds.
A new system and new graphics put high-end mobile phones on the same level as game consoles!
Our first collaboration with Disney's Internet division, the Disney Internet Group.
Trailer summaryFirst thing that was shown, was the ending of Kingdom Hearts II, afterwards the text "The secret ending is solved, and the worlds still extend" Is shown, and then the words "Flow" is shown.
The video then officially begins with Jiminy Cricket looking at his journal, the words "Kingdom Hearts: Chain of Memories" pop-up. He then notices something he did not right in his journal "You need to return, to heal the wounds" Jiminy Cricket then rushes to report to King Mickey. Mickey who is startled by this only replies with "Only he is the one who can solve it." The scene soon changes to Sora standing in Destiny Islands, in Kingdom Hearts 1. However Sora only appears in the form of computer data that is being transmitted.
After the image, the game soon changes to a battle scene. Heartless are attacking, and the gameplay mechanic seems odd, as Sora appears to be moving pies of blocks making it a puzzle game in a sense. Soon the command "Debugging" comes up. When this command is clicked, Sora moves at high speed, and vanishes as well. The scene soon changes to Sora being in Traverse Town with Mickey (As seen in the latest scans) With Mickey saying "I was here on that day." and then "Let's speak truly"
