Action tracker seems pretty cool, everything else was "meh". Not that there was much else shown and I'm not big on playing an "outdated" outdoor game, it's pretty overrated as a feature.
I did read the goalie impressions from community day on the EA forums, outside of his glowing opinion (which doesn't mean squat) he did mention that goalies can shove the forwards in their face, goalies transition from standing/post/butterfly/desperation much smoother which is a huge annoyance as a user goalie.
Goalies will have diff styles and use different saves on the same kinds of shots. Not sure how in depth that's going to be, but long overdue.
Also, no goalies fighting in OTP, however allowed in EASHL, where the RW will serve the 5 mins for the goalie.
