It seems possible , specially since the amazing sales Wii is having... I think halo3 wont reach halo2 levels, and that is becuase its a new machine with not nearly as much installed base as when halo2 was released... I think that was the reason that Halo2 sold better than the first one. With metroid prime 3 being in the console with the most userbase in the holiday season and onwards, and showing the capabilities of the system for FPS GAMEPLAY. It really is plausible for Prime3 to get stellar sales, and get a chunk of the FPS pie. Not by any means overtake it, but being competitive.
