Once Battle.net2.0 is up and running, SC2/Cataclysm/Diablo3 will be released and blizz will be ready to start on a brand new project.

WARCRAFT4 - entitled "WTF! HAPPENED IN THE LAST 8YRS!!?"

Sure sc2 and Diablo3 will have some expansions but they don't take nearly as much resources.

I could see 4 races again. Human/draenai, Nightelf/dragonkin, Forsaken/Blood elves, Orc/Blademaster

"Within the freshest Starcraft 2 panel from BlizzCon 2008 Blizzard proclaims, that Starcraft 2 will be expanded into a trilogy. Furthermore Blizzard verifies, that Warcraft 4 will be released with the same principle."

I demand heroes, auras, scrolls, items, shops, creeps.
I WANT more of the same!!!

I think War 4 if it ever comes is at least 4 years away.
