Yeah man, I really hope the concept of making the virtual football world as realistic as possible and providing options so the User can have as much direct influence as they choose is built on. I could really see some of things you're mentioning coming about due to the "QB AI" tech they touted in the stream at about the 20:35 mark, that will allow Cam Newton to translate his playstyle into the QB AI for his virtual character in M15. I think that tech could be the next evolution of what was attempted with Gameplans under Ian, expanding it out to individual players/positions, not just coaches.
It instantly reminded me of the VIP system from that other football game and it would be really awesome to see that expanded out to all positions. I don't want to get too into this but just imagining the potential for having real NFL and lesser tier football players, player locking on in-game counterparts for Madden and having their playstyle integrated into that players AI would be sweet. I noticed that feature seemed to fly under the radar a little with the community, there wasn't much discussion about it.
