I think there was no other choice. They were completely silent on the PvP front for over half a year, so of course they will say something.
And dueling is just for the only reason so all people won't quit the game right away after reading the blog.
True, and I appreciate Jay Wilson's honesty in the matter but he had 7 months to tell us that PVP was unplayable. Wilson claims that "PVP is not up to Blizzard standards", neither was Diablo 3 but he said fuck it and released it anyway. I was actually looking forward to the Arenas. At this point they should just focus on making the expansion, that's the only thing that can save the game now.
