Adam Swift at MMA Payout thinks that UFC 83 will be a stronger than expected performer on PPV due to the "personal heat" between GSP and Serra:
I expect UFC 83 to do better than expected on pay-per-view. The fight garnered a lot of momentum thanks to the hype surrounding the seemingly real conflict between GSP and Serra. Saturday night fans went home happy with that conflict resolved, however, anyone paying close enough attention got the rug jerked out from the under them by St. Pierre's post fight comments.
