I believe that KZ2 will sell fantastically, but not the 'ZOMG PS3 SAVIOR' numbers that get touted by some... people. I predict a very respectable 3.3-3.6 million.
Red Steel proved that there's at least some market for FPS games on the Wii--the game was very lackluster, yet broke the million mark. With a userbase of greater than 50 million, and with the ad campaign SEGA is reportedly busting out, I would see 2.5 million for The Conduit as a middle ground. If the game turns out to be completely awesome, toss another 1.2-1.4 million on there.
Basically, I see a 'small' chance of TC outselling KZ2.
