I can see SMG hampering the sales of pretty much all games this year (people who're only buying one game will probably get SMG and nothing else unless they're a hardcore RE or lightgun fan), but RE4 will probably be a positive factor. The only RE game on the Wii so far has been a smash hit, and gamers have a very positive image of the franchise in their heads.
It's also the first lightgun game in absolutely ages, so it should get attention from fans of the genre, as well as people who've been going "omg the Wii is awesome for lightgun games, I'm buying the first one that's coming out for it!!!" since the pointer feature was announced.
I'm pretty optimistic that this game will do a million worldwide, although I won't be incredibly shocked if it doesn't, as I'm not sure how well games of this genre generally sell.
