It’s coming fast and furious now. Methinks we’ll see the PTR far sooner than I imagined. Here’s the cliff notes for pertinent information:

• Boss testing will only be allowed during primetime in respective regions.
• Boss testing schedule will be published beforehand so you will know when and what is being tested.
• Some bosses will only be tested in ONE region (US or EU).
• Only a couple bosses will be up for extended testing.
• First set of bosses to be tested are: Freya, Thorim, Hodir, The Iron Council (killing all the good guys eh?).
• Vehicles will mostly only be used in the initial encounter area. Once you’re inside the “meat” of the dungeon there won’t be vehicles (or very few).
• The power of vehicles will scale with your gear (most likely iLevel and quality, not actual stats).

So far the known bosses in Ulduar are as follows:

• Freya
• Thorim
• Hodir

• Tyr
• Mimir

• The Iron Council
• The Flame Leviathan
• Yogg-Saron

I will update this post when and if new information becomes available. Tell your friends to visit if you want Ulduar information distilled down to a need-to-know format!
