RS players are usually completely oblivious to everything other than RS. Blizzcon 2009 ticket was $125. Here's the schedule 2 days, tons of competitons, all kinds of presentations about Cataclysm, SCII and Diablo 3, goody bag and Ozzy Osbourne in their closing ceremony. I doubt Jagex can top that. £75 is way too much. Edit: bah, too late :<
