Someone who is spending $400 or more on a console is not your typical games; being that 75% of all game systems are sold at $200 or less so you'd anticipate that someone who was willing to spend 2 to 3 times what the typical gamers is would be far more likely to buy multiple games.
Beyond the price difference, the Wii has (by far) the largest library of downloadable games with over 150 virtual console games available and 3 new games being added every week. Probably because we have no data virtual console games are not included in the attach rates for the Wii but this certainly negatively impacts the Wii's attach ratio; if people are buying virtual console games, spending their time playing these virtual console games instead of a third rate port of a PS2 game, and publishers are making money off of the virtual console the games should be included.
