When do you think is the most likely release date for 7.3.5? Keep in mind that 7.3.5 has yet to hit the PTR, which will take about a couple of months in itself.
Personally I think that the PTR won't start until next year, and the patch itself won't be released until March. They will most likely not start a very big PTR process in the middle of the Christmas holidays. And there will be a new raid to tie us over until then.
What does everybody else think?
