Red Steele will not sell 1m, because it has no attraction.
The original red steele was purely 'we have motion control sword fightan' which no other game had, thats all, and it didn't do it well, so people won't expect this one too either.
If you look at every well selling game, it has a certain attraction based on its design (usually art), Mario has a sort of wonderland cute funny platformer.
Wii sports resorts is fun arcade minigames with wiimotion
MW2 is of course modern realistic warfare.
