I'm not the least bit surprised, considering a lot of the more popular XBox 360 games can be played online, keeping X360 users glued to the games for the online social perks (chat, lobby, goofing off in between frag sessions, etc.). The Wii's only shortcoming has been the lack of a strong and consistent online infrastructure, and while the absence of it hasn't hindered its success or the number of games being sold/played by the 10s of millions of owners, the drawback is that a lot of Wii players are not continuously on their machines. Real life and other obligations take precedence, I suppose.
