I would give a Diablo expansion a chance but I would definitely wait for reviews this time. Starcraft I'm just not interested in anymore, I have no patience for the monumental learning curve in laddered play and no desire to follow the metagame.
I keep hoping for another actual Warcraft game but I think WoW killed the chance of that happening.
