If you want exclusive developers for your system, then you either offer them an insane deal, or you buy a huge chunk of them outright. I read your feature on SSX coming to the Xbox. It was so cool. Thanks for your time. As for extra features, I would definitely say yes.
Online play is a possibility, as well as additional downloadable tracks as well.
GameCube has it too. Yeah, SSX on everything. EA, like Capcom, THQ and other major companies, is starting to produce cross-platform to maximize profits. In the case of games like SSX, it seems that that means variations on the same game for all major platforms, with tweaks to make each game utilize the strengths of specific consoles. Joe, that means that you won't have to worry about EA games dying out anytime soon on your PS2, or ever for that matter.
