Of course they will be released overseas.
Heres the thing. PSP, DS, PS2, PS3, Wii, 360, XBOX, GameCube, GBA, etc, they are all hardware that are unique. One of a kind. So making a game for one of them and ship them in all continents is not too hard.
Mobile on the other hand, there are about a million different types of cellphones and every cellphone is more powerful than the other. So making a game for one type of cellphone and bring them overseas as well is EXTREMELY complicated. Some cellphones are Japan-only for example...
Thus, the PSP and DS game will come overseas and it isnt too hard to bring it here, whereas the mobile game will probably not come...
