do you actually think if it was a war3 expansion that they would be starting from scratch right now?
it doesnt really matter how soon after it is...im sure when they made war3 there were certain parts of the story or certain things that they wanted to do where they said 'lets leave that for the expansion'
so im sure they have a lot of brainstorming done for the expansion at the very least...i mean you dont leave hte game with such an open end like war3...i mean wheres arthas...without havin any ideas of what to do next
