As would I. little things like that really do add a touch of realism. The commentary is already there in 09, Thorne screaming out "Thats his third! Send in the hats!" and they DID have a hat throwing cut scene in 07 that hasn't been back since. Hope it makes it into the game this year, I also hope they manage to squeeze in some more overlays.
If it doesn't happen this year I would expect presentation to be blown out for NHL11, considering it'll mark the 20th aniversary of the NHL series I'm expecting alot of the "little things" addressed for next years game
