See the one after it
--Edit--
In any case, to get on topic. I would love to see Black Temple before WotLK hit the shelves, but I don't think I will.
My guild has just been trough a very problematic time, where the three main guild leaders are gonna transfer.
But as I am a loyal person I stayed. We were at Vashj. Now we're gonna back to Maggy max, till we can do SSC again.
So, yes, the longer WotLK takes, the more content I'll see.
As I am no casual player, might get lucky.
