The video is a fake, and has graphics elements and game elements, such as the bags, that are indicative of a private server. Additionally Kuoccino points out to me in a later email that the steps are really benches from the Undercity, and that the throne is from the Undercity as well. I'm inclined to agree with him.
Normally I wouldn't post something like this, but it's a good example of how far people are willing to go to try to get a scoop on WotLK. Also, as Mike Schramm pointed out on the podcast this afternoon, now is about the time that we'll start to see more leaked WotLK information. The alpha is going on, and the beta is a few months away - this is prime time for leaks to happen.
Now of course, there is the remotest of remote possibilities that this video is real. If there is even a smidgen of truthiness in here, my hat is off to the person that got this.
If you've got any WotLK screenshots, real or fake, hop on over to our tip line and send away! We're always on the lookout for a good thing! We just reserve the right to laugh and cackle if you send us fakes.
