Why do people think Kairi's become a keyblade master? That might have just been Riku picking his first student since becoming a keyblade master. 'cause he's not gonna train Sora. And, Lea looks like he's being trained by Yen Sid.
And, I think that the new game the secret message was talking about could be that BBS Volume Two, if they are making that game. It wouldn't make sense for it to come out after KH 3. In the trailer for BBS Final Mix, they called it 0.5. So, it could be that new number.
Also, before someone says " No! The next game that comes out is KH 3 because 3D said it leads to 3". I think that means that Kh 3 takes place after this game, but that doesn't necessarily mean it's the next game that comes out. I think I read somewhere that Nomura said that he'll start to work on KH 3 after FF Versus 13 is finished, whenever that is. Since we haven't seen too much from Versus, I think it'll be a while before Kh 3. Maybe two or three years. And, I think they might re-release KH 1 and 2 for the vita and ps3 before 3 since it's been a long time since their release.
After seeing this secret ending, I was thinking about about the plot for 3 will involve Sora, Riku and Kairi each saving some of the people that popped up in blank points in BBS while having to deal with Xehanort in some way. Sora might go after Ventus in Castle Oblivion with Donald and Goofy, Riku might go with Mickey (and maybe Lea since he was friends with these two) to find a way to bring Roxas, Xion, and Namine back, and Kairi might go into the RoD to find Aqua and Ansem and bring them back. That way they could have all the keyblade wielders together, fighting Xehanort.
Also, I think sora not becoming a keyblade master, while riku does was a good choice. I think sora deserved it, but it would have gotten in the way of KH 3. Nomura would have thought to have him teach kairi or something. Sora's better as a keyblade wielder, anyway. That way, he could run around with donald and goofy like he always does.
So, thoughts? (Sorry for the incredibly long post. This is my first time ever doing this kind of thing and I had a lot to talk about with this subject)
