Cataclysm guild stuff - important!

Dark Phoenix Mount Reward
The guild rewards you guys are seeing in game are not hooked up yet. Guild rewards have 3 requirements that must be be met before you can use them. First and foremost, they must be unlocked via a guild achievement. Let's just say, that for example, you need to complete the new guild achievement "We are Legendary" in order to unlock the Dark Phoenix. That achievement requires the guild to gain access to all 6 legendary weapons currently available in the game. (note that all guild achievements start on Cataclysm launch, so anything you have now will not matter, it must be done with your guild after launch)

So, let's say that your guild get's this achievement and thereby unlocks the Dark Phoenix on the guild vendor. At this point anyone in the guild can see the item on the vendor, but they will need a specific amount of guild faction to be able to purchase it. In this case, let's say exalted. Now, once you have the guild faction, you can purchase the item for its gold price. (prices will vary based on the reward)

I am using the Dark Phoenix and the We are Legendary guild achievement as examples here but you should get the idea. Don't worry, we wont be handing out all the goodies so easily. =)

Emphasis mine.

Guess we should start doing some MC runs to pick up some bindings, BWL for elementium, etc.  Getting the WOTLK ones after launch will be a pain though, if those stay 25 man only..

Of course that was just an example they used, but can't hurt to farm up some items to turn in after the system goes live :)

I imagine 8-10 people geared for Cata raids could very likely go back and do 25 man Wrath content.
