Well over a year ago I said 360 and I still think I'm going to say 360. Although Wii has close up the gap some, 360 is still getting the majority amount of big games that are able to open to enough sales to hit the million mark. And despite Wii having the larger userbase which means more long term million sellers, with only the Nintendo games being able to do what those certain 360 titles do, it's a longshot to me. PS3, unless it gets a larger userbase, it is hard to think it'll be able to get more than the 360. Not to many PS3 titles that have sold a million and are 3rd party compared to 360 (if there is any).
So I'll say 360, but this all could be strongly affected by when N6, Xbox 3, and PS4 come out with some being as early as 2011/2012 and as late as 2013/2014. That could really affect this.
EDIT: although I will say Wii has caught up at a faster rater than I first would have thought. It's going to be tight between Wii and 360 over the course of 2010 and 2011. So when I say 360, if it does beat out Wii, it won't be by much.
