KZ2 by a far far amount. I know people are discussing the userbase, but much like the install base of PS3 being Blu-Ray only,a good portion of the Wii install base is non-fps demographic.
Also, in the thick of a holiday season, if a CoD game on Wii can only pull off 600k then the Conduit doesn't stand a chance. CoD is too fps, what final fantasy is to rpg's, it's the king of them. New IPs for rpg's don't sell well, and neither will this.
I might get some slack for this, it is merely my opinion but this genre of game is the area where the Wii needs to prove itself the most...
One last bit, FPS fans pay attention to reviews and metacritic. If the Conduit gets any "Hazey" reviews....then no...
