guys, PLEASE, you must be new.
there is no point in "guessing". Sometimes we get patched at the exact same day sometimes we get patched about 3-9 weeks later (yes yes) or like in TBC case even over half a year. lol...
but this is china, the country that tought me patience. what difference does it make?
so, rule of thumb:
PATCHES ALWAYS on the NIGHT FROM MONDAY TO TUESDAY during server maintenance. Any other day there won't be a patch.
another important rule: DONT GIVE A DAMN which patch is out in the USA / EU. if it is not out yet in china, you can feel free to download it, but for christ sake, DONT INSTALL IT, or you simple CANT PLAY anymore. And as the patch sometimes takes WEEKS to get out here, you might be royally screwed.
So use some Download link from wowwiki to download it or whatever, but NOT the automatic download thingie from blizzard. try to disable that, because once Download is done it will auto-patch your game without asking you.
Another thing, on EVERY patch, the realmlist.wtf gets overwritten and re-set to EU or US servers. so you will have to re-edit again, and we will have to answer the same question "i patched and now i can't logon to the game anymore" questions here again.
Good luck, keep waiting, stop guessing, enjoy the game, and when a patch is out, its out. until then, simply play
