It depends on how long SE's known about the NGP. When the 3DS was announced, SE already promised a FF title (probably another Crystal Chronicles title, but I'm hoping for another TA title or sadly enough, FFVremake) and KH3D. I wouldn't be surprised if it was for the NGP. Considering its slated for a winter release, I have a feeling most developers knew about it fir awhile. On the other hand, Sony has already said they have no plans on shelving the PSP when the NGP is released so it may be very likely that BBS2 will be released on the PSP since the team already knows how to work on the PSP hardware and can probably reuse a ton of crap from the original. So a quick release within a year is not unlikely, look at FFXIII-2.

I'm hoping for a PSP release cause I already own the platform and have no plans to buy either the 3DS or the NGP until they get more substantial game libraries (and a price drop, ouch Nintendo...). Oddly enough, I'm more excited about BBS2 than KH3D.
