Catch i would say you may be better waiting till the Patch/Update comes out for 2k9, it was supposed to be out last week but someone posted on 2khockey.net that there has been a delay and it wont be out until this week or next.
I would wait till then if i was you, i have both games and in 2k9 there is just too many spin o rama's and the AI just drives the middle constantly. if they do patch it hopefully it will be addressed because if it is i think it could really be a good game.
