There will be a great deal more in the patch than what the blues have revealed so far, so take these as only partial lists. Also, a few items Blizzard hoped to get into the patch may not make it. This is the unfortunate truth in the development process.
World of Warcraft Lead Developer Jeff Kaplan, aka Tigole, mentioned that Patch 2.3 may hit the Test server this week. This seems very likely since the current patch on the PTRs, 2.2.2, must move off for Brewfest to go live on Tuesday.
