That's tough...
On one hand the world would have as you mentioned starcraft 2, diablo 3, and possibly KotOR 3. Many WoW addicts would have lives where they would continue to live in ambivalent states of misery and some of those are friends of mine who might actually go outside once more and face the harsh, bitter world that awaits them.
I'm not sure yet, if Blizzard's commitment to success was due to their ability to work well under financial pressure and with WoW they slack because of their financial success and it shows in SC 2 and Diablo 3, I will scream.
