I don't know why I thought it was merely a contract - I guess it's just hard for me to imagine Blizzard not being it's own company (makes me sad).
Blizzards motto is essentially, "it's done, when it's done". They have the track record to back up there product, so it seems like investors are lenient with the developer. Most publishers end up pushing games out to soon causing them to fail - this never happens with Blizzard. Blizzard is currently working on a successor to WoW, and Diablo 3.
Perception in the gaming community towards activision and EA is very poor, however, they are undoubtedly creating more profits. This year is going to be very big for the industry as well - battlefield 3 and mw3 are both releasing this holiday which are to my knowledge, the biggest money makers for EA and Acti. (edit: I meant for the console. WoW surely makes the most money of any game)
If you're really interested in trading gaming stocks, I would suggest following and anticipating the major gaming conventions held throughout the year, such as the recently completed E3. We are nearing the end of the current console generation too. Usually console generations last around a decade, but with Nintendo already pushing new devices, the pressure will be on microsoft and sony to get their new consoles completed and ready to go. These announcements could still be 2 or 3 years away though.
