Servers aren't quite up yet, but you can download the new patch for Diablo III today. Estimated time for servers to go live still seems to be 2 pm EST. In the meantime, check out the patch notes listed below.
Interesting things to note:
The guaranteed legendary drop for Skeleton King has been moved to Diablo, available for level 60 players defeating Diablo for the first time, or after using the "Reset Quests" option.
New +Max Spirit affix on select items for Monks.
Crafting changes to Legendary and Set Piece items, now requiring two Fiery Brimstone's instead of one. We might see an AH price increase on that one before it gets pulled down.
One disappointing absence here is no fix for the current state of 2H items. Currently 2-handed items roll 1-handed stats, making them significantly weaker. Hopefully this is something implemented sooner than later.
