The Behemoth are a small studio I beleive so porting to PS3 seems like a big thing but the next logical step would be the PC since the port job would be a lot easier and would probably garner reasnobly good sales on steam (for a port of an old game mind). For them to port to the Wii would be a lot more work like recoding the engine and remaking a lot of the textures so they work at a smaller size which might not be feasable for a small production studio, especially considering the size of there games meaning its likely to be a WiiWare game which dosent seem to to get great sales, and the majority of the people who want it have it and it dosent appeall to the Wii's casual crowd so, from my perspective, the cost and time outweigh the potential sales.
