lol! I cant wait for all the defenders to be "shocked" when they announce all this stuff is being pushed back to the expansion.
Well from what I've read and seen in the Q&A, the plan has been set for sometime. Speculation on my part, but from the interviews it seems these things are being treated on separate time tables. And we know that the next major patch, 1.7 will be Illum.
My guess is that they will remain separate as they have different teams working on them and they are at different stages in the dev process. Pretty common practice. Only time will tell. But we should know in mid Jan.
