NBA 2K12 will be arriving for iOS devices on October 4th. $9.99 for the iPad and $4.99 for iPhone and iPod Touch. Check out the exclusive at CNET.
What's most important is the gameplay, and 2K12 plays smoothly; players on the floor are well spaced and the animations are great. Basketball is more than just dunking, and its not that easy get to the rim if you want to show off. The broadcast-TV-style presentation really separates it from other iOS sports games, with full commentary and replays that add extra polish.
There's so much content and different game modes in 2K12 that it's worth the price of admission. You have the standard Quick Game; there's a full 82-game Season Mode with player transactions; Playoff Mode, where you'll skip the regular season and jump right into the games that count; and Situation Mode, which allows you to create custom scenarios where you can try to comeback from 5 points down with a minute left.
