Since this is impressions, I thought I'd share my impression on the lighting. Well, all I need to do is post this screen shot I found at the 49ers official forum:
For the first time ever, Madden as captured the lighting effect on the 49ers helmets during a night time game. The resolution is bad because it's from YouTube, but this just looks stunning to me. Especially in motion, because the bright yellow-gold blob thing moves very similarly to how it does in real life. I didn't think they could ever do it, but they captured it. Very stoked about that.
