If you purchased a CS4 within 30 days of new release you get a free upgrade to CS5. Because the friggin' bank, credit card co., and software company kept fuckin' up my order---I didn't get to complete my purchase until the 15th. I noticed CS5 release today. I just came in under the window. thank you customer service for fucking things up---sort of. There sometimes is a silver lining in a cloud.
