Of course they aren't, Blizzard doesn't respect deadlines at all. Everything is late from them. It's for the best though, look at how D3 turned out. Years and years of development, extensive testing, all the annoyance, but when it came out it was the best game ever made and was completely perfec...... wait.... wait, that was a dream I had. I remember how it went, years of development time, broken on release, no more fun than the last game, dated graphics....
I return to my original thought, is anyone surprise by this... I didn't think so.
