The demo itself plays better than any basketball game that's ever been released, that's hype enough on its own :s
Also, the demo doesn't include playcalling, commentary, and the dynamic attendance and overall presentation additions aren't in there. Also, the demo is stuck on a specific game style, most probably the casual setting and pro, so there's no challenge, and limited AI plays, so you can't fully enjoy the game. But in terms of gameplay, controls, and likeness to the real deal, it blows away every other NBA game released, so that's hype enough, not sure wth you're expecting from an NBA game
