Fairly quickly = 3 months+ for bugs rated as "Urgent" (second biggest priority in Bugtracker) and even 8 months+ for High priority (3rd ones) bugs along with Immediate bugs that are the highest priority ranked reports, and I see some of them since 8 months too.
Anyways I hope you love to do battlegrounds, if you don't then you won't have too much to do at the moment. There is two and half (MSV, TOES, Five bosses ToT) raids open in 10N/25N difficulty.
One of the most important reputations are bugged, so you cannot purchase good starting 496ilvl+ JP/VP gear, so if you want to do PvE you better start farming Tyrannicals
At the moment there is WSG/AB/EoTS/Twin Peaks/Kotmogu open, don't get frustrated if you and your 300k hp mates face full Grevious team beacuse its normal, but I don't count player's *****ism as any kind of server fault (people who cannot buy Contender's Gear, 1,500g for 8/8 set),
Emmm... what else, oh have fun with Cataclysm leveling zones, remember if you are bored you can always have some nice conversation with opposite faction member, since you both understand each other's language.
Also if you curious about old contect check this thread
