Incorrect.
I will admit that PhantomSpinosaur was on the right track. The sequel was indeed Land Before Time 10, and the problem that was solved was the fate of Littlefoot's father, where he has been all this time, and the fact that he was alive.
The only thing he got wrong was the conflict that arose from the realization that Bron was alive. Bron himself, with his story he tells to Littlefoot, conflicts with the original LBT. Bron's story, so far, does not make sense with the events of the first movie. The pieces don't seem to fit together.
