When do you think it will be time to MOP things up?

Sorry for using the really cheesy pun lol.

But what I mean is, when do you think MoP will end, or in other words, the next expansion will be out?

I'm thinking December next year?

Seeing as they will probably release details on the next expansion at Blizzcon.

What do you guys think?

(Not that I want MoP to end of course, loving it in fact)
