Zarhym announced on the forums that the next patch is coming, and it's going to be a big one. The particular of that news, however, they're going to turn on the background downloader to start its work "shortly." Shortly, in this case, means soon enough that Zarhym supplied some tips to how to control the speed of the download.
We're expecting all that content they've already promised, which includes:
- New class spells and talents
- Stormwind harbor
- New Arenas
- A built in Guild Calendar
- New Hunter pet skills
- No more Zul'Aman bears
So, the word's pretty much out. If you have goals you want to accomplish before the content patch hits, you better get them rolling along. You don't have much longer.
