I think there is a real point to make here, possibly. As others have said: Red Steel was hyped like crazy, and when it didn't perform well, Wii FPS games have been doomed to hell ever since.
I don't follow Move, so I don't know how anticipated this title is, but it could very well have some effect. The only difference is that we're talking about Sony, not Nintendo. Nintendo has always been doomed doomed doomed forever. Even with the PS3 falling incredibly short of expectations, developers still cling to it and produce games for it, never giving up hope. It's the exact opposite story for Nintendo, exact opposite.
After thinking all of this through now, I think this game won't hurt at all. We're talking about Sony, not Nintendo. This game will be merely brushed aside with plenty of kickass games to cover it up in the near future, so don't worry.
