Well, I say PS3/360 is the best choice. It get expensive just when you want push graphics hard and Atlus is knowed to don't give damn for pushing graphics, sure they have superb artwork and design but not graphics. To make an okay graphics game it should not be that expensive, even considering Persona push for SD/Cel-Shaded graphics, something looking better then Persona 4 is already good.
For sales I think PS3/360 is the best choice, North America is important for Persona sales and we know both wii don't sell this kind of game because of demographics and putting in PSP the sales in this region would be killed. For Japan PSP is the best choice, but, release in PS3/360 sell will be okay with both systems.
