Nothing but polishing changes being made on 7.2, seems to be the last interview for the patch this week so we can assume that the trailer and announcement date might be made this week. When do you think 7.2 will be announced and what do you think the trailer will be based on?
EDIT: Forgot to add. I also speculate that the trailer may focus on Aegwynn, Gul'dan, or even the fallen avatar.
