From 1up.com : "While much of the game resembles the impressive just-released 360 version, one of the key new features can actually be found within the confines of the system's controller. The tilt function in the PS3 controller allows players to try out their follow-through motion for free throws using the motion sensitive capabilities.
Graphically, Visual Concepts president Greg Thomas explains that the developers have been able to process more "math" through the PS3 architecture, helping the performance and the aesthetics of the game. We couldn't really see an immediate difference beyond some better reflective textures on the court and the sweat that appears on the player models. With no 360 version present, we weren't able to do a comprehensive comparison, but it seems like the PS3 game will be a small step forward."
