Edge: Art and quests aren’t the whole story. There’s an entirely separate game within World Of Warcraft that means more to a certain type of player than levelling a character or exploring the world ever could. It’s a game that requires intense cooperation and extremes of coordination. It’s raiding. And in raiding, Blizzard is cementing a new kind of cooperative entertainment. The core idea: get a big group together and beat the tar out of opponents in carefully choreographed, mechanically diverse fights.
Leading the raid development is Scott Mercer, a Blizzard veteran who graduated from the Warcraft and StarCraft teams, and who has a controversial view of how WOW raiding has found success.

Apparently Cataclysm won't be the last expansion for World of Warcraft and a blue commented on the number of changes in Patch 4.3.
seriously, I'm sure they'll make another one or more after this as well. WoW is still a HUGE cash cow
Blizz hinted years ago that they have a few more expansion ideas lined up which would eventually take the level cap to 100 and beyond. Given that Cataclysm only raised the cap by 5, and the new expansion does the same, we can assume that there will be at least 2 more expansions.
