WOTLK content

Hello, maybe it is too early to ask, i was browsing lordaeron forum but i did not came across any information about the information about plans for WOTLK content. My question would be is there any confirmed source about how will they release wotlk dungeons. will they release everything at the same time or will they realease the content in parts/tiers what ever you call them. First Naxxramas/Eye of eternity/Obsydian sanctum then undual and so on?

Progressive realm so it will be released in tiers. Example FoS/PoS/HoR Wont be released at start but when icc gets released and so on.

Well. Awesome. :) Thanks. But any GMs/Owners/Mods confirmed it?

You have it on the thread Lordaeron information it was stated countless times it will be progressive. And np.
