Well, I'm interested... As long as they can nail down the controls much like Metroid Prime 3 did. I'm all for more FPS's on the Wii as long as they actually take advantage of what the system has to offer.
I think the Wii needs more mature (not exactly sexually mature, but more grown up) games in its library. I enjoy the Wii, it's been one of the most fun consoles I've bought in years, but many of the games are just too simplistic, ports of games showing up on every system (such as the Lego series of games) or they are sports games (honestly, do we need a new Madden game EVERY year?).
