That sounds far too optimistic. I'd imagine if they did decide to put BBSv2 on the PSP2/NGP it wouldn't be too long after the console was out. At least not long enough for a price drop. But that's just my opinion so take it for what it is.
Lol, the PSP2 is going to cost around 300$ on release date, and I'm pretty sure Square-enix staff aren't Flash, the game will take at least 2 years (minimum) to come out.
