MoP is releasing this year, and not the end of the year like we're used to. Blizzard is going to be in full-blown panic mode as you can see with two of their big projects in various troubles, and one expansion pack for a RTS that should have came out a long while back. MoP will release in summer this time, or end of, because they know that they can't rest with Guild Wars 2 and company getting soo much media and fan attention. Mix in the luke-warm response to the MoP expansion, and they're very-very concerned. I mean, they're not even cashing in on another Blizzcon, something it's fans looked forward to yearly. Which means they have nothing to show for it, which is of MAJOR concern because that means Titan is in massive trouble. You would think they'd show something off about it to get attention away from GW2 and company, but they have nothing.
This is when we see some major restructuring within Blizzard. Their time frames were out of control, and they're going to start embracing consoles now as well I'd bet. Maybe this will be the kick in the pants Blizzard needs to be a great dev again.
