I've heard about this as well, but am also waiting until I hear an official confirmation. But as for my thoughts at the very moment, I'm honestly not too interested in the remakes as of this moment. I've played and got 100% on 64, Galaxy 1 & 2, 3D World before and not really interested in replaying them currently. Maybe I'm getting old or something and this doesn't get me as excited as it used to (though the Xenoblade Chronicles remake is coming out and I'm looking forward to that so not sure)
A new Paper Mario that goes back to the traditional format would be enticing, but I'm not getting my hopes up on that yet.
