Zul'aman
Gamesradar.com posted a preview of Zul'aman. Frictionless Insight also posted one. Only a few things are new :

• Zul'jin and his enclave of forest trolls have found a way to infuse themselves with animal spirits.
• You will have to chase Narolakk (Bear God) through the instance before you can fight him.
• The bear mount droprate will be stupidly low, same as the [item=19902]
• Zul'aman will feature 6 boss, the 4 animal gods, a Witch Doctor, and Zul'jin.
• The very first monster of the instance will be a boss.
• The 4 emprisonned spirits will help the raid during the fight against Zul'jin.
• There are 4 prisoners you can save, it seems that they will die overtime. You'll have to be fast if you want to save all of them and get the uber loots.

For more informations about Zul'aman you can check the Zul'aman preview #1 or Tigole's post about it.

2.2 on PTR
Hortus posted a few things about the 2.2 patch on the PTR. The most interesting information is the confirmation that the Guild Banks and Zul'aman won't be in this patch.
Quote from: HortusPre-mades
Because of the very high level of interest in pre-made characters for the PTR they copy systems is very busy, the queues are very long and may take several days before your character is available. We are aware of this and the only solution is to be patient.

If you get an error when trying to copy a pre-made it is because the queue is full and not taking more requests, try again later.
