I'm in the same boat as Que. I hope to god they're not trying to make an MMO. Not because it doesn't have the potiential to be good, but because it'll be a waste of money and time if it tries to go against WoW on any level.
A straight out RPG could be cool, but that's a pretty big step. At least when Blizzard went to WoW there were obvious trimmings of things they were playing with in WCIII. Relic doesn't have a ton of that going on in their games.
