Just two weeks ago, Jay Wilson tweeted that a blogpost on Diablo's PvP will come "very soon". As he'd later go on to delay said blog, players now receive another vague ETA.
That's at least two weeks of waiting before light is shed on the long-expected feature and a confirmation of what many already suspected: PvP will not be available until 2013.
@piggilol We are not likely to post a PVP update until the end of the month. Note: that is not a promise. That's all I'll say about that.
