Lol, of course its not out yet. Are you in the habit of purhasing things before you determine if you will enjoy them?
Plus, the new reskins have already been revealed in depth. I dont have to play the game to see that Tauren with moose antlers and Draenei with yellow tattoos are complete and utter cope outs.
I'm pretty sure Blizz is just in the final stages of WoW, where they know their numbers are at the lowest point they've ever been. So they're just throwing shit in for the players who actually still sub, knowing it wont matter much anymore. That's why Classic was announced. That's why they're putting elves in everywhere.
I predict BfA may be the last or nearly last expansion. It feels like a big reset meant to wrap up some story lines. WoW 2 will be announced soon.
Im usually right about this stuff. I successfully predicted both Pandaria and WoD expansions. I think i just have a knack for looking at things more objectively than most you nerds who are so attached to your characters.
