The whole physics engine thing is the way of the future for NBA games, but I reckon Elite won't need ANY basketball knowledge at all in order to succeed, whereas with 2K11 the more basketball knowledge you have the better you will be at it.
Elite will be smooth and polished but for what it is, which isn't a real life basketball simulation game, but is just a basketball game. 2K will eventually step up to a physics based engine but they have the necessary basketball knowledge to implement into the game in order for it to take actual basketball skill and not just gaming skill to play.
That's what I think the difference between the two games will be this year. 2K = Real Life Basketball Simulation,
Elite = Basketball GAME
