Well, I think that BBS Vol2 could perfectly go to PSP or PSP2:
-For PSP they could make the game relatively fast: same graphic system, maybe same worlds... the only thing would be the new battle system (if they improve it)
-For PSP2 it's also possible because of the news that some months ago told us that a lot of companies were working with PSP2... but the development time would be longer (each time you start working for a new system is hard)
So if i had to say i would say that BBS Vol 2 will be for PSP(more or less same benefits, but less production costs.
Now talking about the Secret Ending, a fact that i think is very relevant is what a user said some pages before: Riku at Neverland; in re:coded "data Riku" shows "Data Sora" a video of him trying to "catch the moon" and now at this secret ending we see riku with kairi again in the same place, it has to be some mystery in it...
To end, my first appearance in this forum: at the end of the secret ending we see Ven dissapearing, also we know who was trying to find Ven in KH2 FM, the one that built a chamber (awakening was called?) very similar to Ven's, that one was Xemnas, maybe Xemnas found Ven... What do you think?
Greetings to all!
