To be fair Blizzard does make stuff miles in advance. It's plausible for a 5.5 trailer to be already made and then they just work on the details from now until then. When they made the MoP trailer they said something like that takes like a year. A less intense patch trailer would take a couple of months so yeah, this seems possible to me. It's also nearly too good to be a fake imo.
A: We don't have plans right now to express that in the world in 5.4 -- there's an event that's going to be taking place between 5.4 and the next expansion, assuming there is one of course. (laughs)
Would be so funny if this was actually leaked by a Blizz employee intentionally since they knew it was going to be called a fake. Actually after Ghostcrawler's Statement @ Legendary it would be so funny if Metzen was going to Announce it on BlizzCon. No one could say there has been no REAL leak Prior to Blizzcon. Honestly.. that would be REALLY fucking awesome.
Wonder how Skysunder would be related to Warlords of Draenor, if it will be the expansion. Sundering sky and time travel does not make much sense o: Unless azeroth gets destroyed and we have to abandon it by traveling back in time. So many possibilities!
It isn't because this is fake.
