I'd say the 360. It's too easy for 360 games to sell a million now,and Wii's sales tend to focus on the most popular titles. For example, the 360 will sell 5 shooters over 1 million, and the Wii will have one game do all 5 million on its own. PS3 can't catch up because too many of the games sell over a million on both 360/PS3. There just aren't enough exclusives to overcome the 360 exclusives as well.
Just look at how many likely million sellers 360 has on the slate for the rest of the year, and I find it hard to believe Wii will catch up any time soon, even with the couple random Just Dance-ish types popping up from time to time.
