Between the 360 and Wii, I expect almost multiplatform games to do better initially on the 360 with the Wii versions making up the difference in the following months (especially Tiger Woods). It's a general trend I see for most comparisons between the two consoles and will probably last through the rest of the year.
Madden = PS2>360>Wii>PSP>PS3>XBX>DS It'll clog the Top 10.
Bioshock will do about 350k. The hype for this game was rather last minute; it's was completely off-the-radar for most people until just before release and I don't know how will far past the hardcore that hype went.
MP3 will probably only do about 200k (possibly less) partially because it was on shelves for such a small amount of time last month. I think the hype for the game had a little more reach than Bioshock, even if it wasn't as intense. Given the history of the release date for Nintendo, 200k would still be a very strong opening and I expect MP3 to easily outsell Echoes over time.
Boogie .... I don't know what to think of this game. When my store first put it on the shelves it sat there. We sold nothing (literally zero) for about a week. Then a few moved, and then, that following weekend, they just dissappeared. I can't decide if this game will be a huge bust or hit.
Brain Age 2 = modest start. I'm not expecting a huge first month.
