Maybe its gearing up for the DLC on Thursday and then they can say its not so bad becuase they patched a few issues days before charging for the DLC?
Re the PS3 version, I can't see them eliminating many of the current bugs (freezing, bumps etc) though, they've had a few goes at it and more and more keep appearing. Its still a very enjoyable title (I've won over 500 races online, lost a fair few too lol) but it doesn't run perfect and it could of been so much better if it were not for a just few issues (aweful punting online so much better penalties required against cheats, random lobbies is just a farse, abilitiy to change the ffb stength).
I suppose they have to make the most of it because when GT5 comes out Shift will probably be the last NFS series many PS3 racers will ever buy.
