I've had 3 freezes so far. To the best of my recollection:
1) Was true freeze. Audio/Video frozen no response from any button actions etc... I believe it was during preseason and I was heading back to the main screen after a preseason game.
2) true freeze again. preaseason>coin toss screen
3) "Eternal loading" Week 2 of career (Buf) mode "Loading" (Buf@Jax) On splash screen that says "Loading" and trivia kept running and changing. I think I got to read almost every trivia bit though
PS3=40gb less than a month old...do you want serial # or anything useful like that? PM if you want any additional info I guess
Had to shutdown for all 3 incidents.
Oh, one last thing... is there any gameplay difference whether you're hooked up online or not? (besides seeing the ticker)
