There is supposed to be one more reveal left for M15. Some game changers have hinted at it although I don't know what it is.

Also, the demo info has to be released very soon. Madden many times has a demo out 3 weeks in advance. That appears out as that would be tomorrow so it's a very good chance that we get the demo next Tuesday, August 12th. I just hope the PS3/360 gets a demo. There has been so little information about this version I am nervous.
