According to MMO Champion, Blizzard confirmed today that Wrath of the Lich King has gone Golden master and is already in the process of being manufactured. The company is merely putting the final touches to the expansion. This is expected preparation for the launch date, which is only a little over a month away. This also means that all subsequent changes that happen in the current Wrath Beta will be applied in future patches, possibly even as the game is launched on November 13.
I was curious as to what Beta build had enough features -- and stability -- to pass muster and make it to the Golden master. Is it the latest build of 9038 or would it be one of the earlier builds? But as Eliah astutely pointed out to me, there will be patches applied quickly as the game is launched, rendering whatever build is on the Wrath DVDs somewhat irrelevant, anyway. Even now, the Blizzard background downloader has over 1Gb worth of content ready to patch on Tuesday.
One thing is certain, however. There seems to be no stopping the Wrath of the Lich King now. When the Echoes of Doom start sounding in a few days, we're all just be counting down the days until the DVDs that are now being pressed, packaged, and sealed make their way into our greedy hands.
