I think it's mostly this:
It's now been a week since the game was "officially released" and the rosters, sliders, and online dynasties still don't work. We've known for months that there was no defensive pressure, returns were broken, and that short passes were impossible to stop, but were assured by stooges and developers that those problems were minor and would be fixed by release.
As AA said, the new features range from poorly implemented to unusable, and the gameplay has serious problems. This isn't complaining just for complaining, this is the most buggy console game I've ever seen.
