I'm not surprised by this delay. Blizzard seems to put all their resources into WoW, leaving the rest of their line rotting. Maybe they could take this extended period of time and fix the things they've been doing that are ruining this game.
This real money auction house is BS, Blizzard has no business making money off of item trades (changing the drop rates of items so that certain the quantity of certain items remains low so price remains high in their market is a total conflict of interest.)
And this on-line only is BS, what happens when my connection goes down? what happens when the blizzard server goes down? How am I supposed to be able to play the game that I've paid for. This is one of the reasons why cloud computing is ridiculous.
I won't be afraid to return this game if it's a complete let down (as I'm afraid it will be), besides, by the time this game actually releases I'll probably be over it.
