From the The PS3 difference part of review near the end:
"Sadly, just like with NCAA Football 08 and All-Pro Football 2K8, PS3 owners are stuck with an inferior version of Madden. While the game runs at 60 frames per second on Microsoft's box, Madden only clocks in at 30fps on Sony's console. The result? The gameplay isn't nearly as smooth as the 360 version and even stutters at times."
