The preview is up on ign's website, and I'm intrigued by the number of new formations. They had 3 "experts" watch every team and copy plays for their playbooks. There are 86 new offensive formations and 16 new defensive formations with over 270 new plays.
Other highlights (IMO):
- QB's have more widely varying arm strength.
- More emphasis on special teams including more trick plays for special teams.
- More trick plays in General.
- Defenses more geared towards stopping Running QB's with better spy usage, etc.
I'm curious to see how the momentum meter is re-implemented.
Here is the full preview from IGN:
