I just got done playing both versions of the game at a friends house and posted my impressions in another thread.

There are no lag issues on the PS3 with the button presses, whoever says there are hasn't played the game.
I've been playing madden since 1993, and I would notice for sure. It plays almost exactly the same as the 360 version, the only difference is that it's not as smooth.
So if people complain about lag issues just ignore them. The game stutters at times, but it's in no way a deal breaker like I said in my other post.
