NHL 07 for the PC looks exactly the same as NHL 06, so those of you looking for a jump to next gen on the PC will have to wait for at least another year. The primary difference between NHL 07 and the previous game is that the Passing button has been remapped to the Right Analog stick on your game pad. This took some time to get use to the new control scheme, after adjusting the game plays very much like the predecessor.
There are some tweaked puck physics, and the removal of some of the trick shots from last year, which seem to make the game slightly lower scoring/realistic.
The main improvements have been to the dynasty mode, which now can be played in several different leagues.
All in all NHL 07 has a couple modest improvements from the previous game, but really doesn't offer anything new, besides the control scheme. If you haven't bought a hockey game in a while go ahead and pick this one up, if you have NHL 06 don't bother updating
