No one knows what system it is coming for, its just conjecture at this point. As I said before, I think it depends on how far a long Overworks was with the SoA sequel for GC. If the put any significant work into the game, it will probably be Wii. If not all bets are off. Sega/Sammy is cheap, I don't see them scrapping all the work from the GC version unless it never made it beyond the planning stages.
