Update: It has been confirmed that they will be delaying the patch to either Saturday or Sunday.
Thank you for your patience! Should any changes to this schedule occur, we’ll be sure
True to the pattern of recent patches for the Diablo 3 Beta, Patch 13 may be delayed until next week. Dates are never promised, but that doesn’t prevent the community from getting their hopes up yet again. This isn’t to say that the next patch has no chance of launching today, it’s just very unlikely with the following tweet:
The previous 3 patches have all been delayed by a minimum of 6 hours, so it is no real surprise that this patch will be delayed as well. It will certainly be a pleasant surprise if it still goes live before the weekend.
As a small recap: fans speculate that this patch will include runestone/skill changes, the newly implemented chat lobby, the recently announced auction house changes, and tuning for the Demon Hunter or other heroes.
With a laundry list of changes that long, there is little wonder as to why it might be delayed
DISCLAIMER: Not all of these changes are promised in the next patch, and are purely speculative.
