I agree with all those who say there seem to be logical holes in the OP, but there is a way this could be nevertheless true and somewhat make sense, and that is if Nintendo will be paying for the localization (and maybe will publish the game in the West), under some contract saying that the localization resources for the Wii version can't be used for any other version (so to localize the PS3 version Namco would have to pay themselves).
In such a scenario there will indeed be a Wii version, and since originally they had no intention of spending ANY money on localization, Namco would wait to see how well it does before they decide if to spend money on localizing TOG F out of their own pockets.
