I doubt they would leave Sora out. Nomura has always said that KH is Sora's story and any numbered title would have Sora as the main protagonist. Also, Ven and Aqua are too important in the Xehanort saga to not rescue them during the same one. But, only time will tell.
Well, I can understand if someone doesn't like KH. But this guy doesn't really seem to understand the series as a whole. He thinks that because the story is complex, that it is horribly written? That is just very ignorant on his part. Oh how silly.
Yea, probably not. In NA, the PSP bundle we got was just the silver PSP-3000 with some KH stickers for the back. I hated how the bundle didn't even come with a game case but thats how all the PSP bundles come. It's annoying.
