I choose the Middle Path
Anyhows as for the graphics, haven't seen the thing yet but uh... it's not like they could really offer you a glimpse of PSP2 graphics on a PSP game's secret ending, right?.
well that's true but ussually they show cgi, I think that meens they've already started to work on it and I doubt they want to improve graphics that much later. Seeing as PSP 2 almost have PS3 graphics I don't think they will put the energy into it before KH 3 (and it haven't been confirmed by SONY)
I have convinced myself, it's on PSP (or possibly 3DS but I strongly doubt it for severall reasons)
