I just really doubt that its going to be that date. Launch is looking to be in December and people (even with the gimped zombies) won’t want to stomach anything longer than 2-3 weeks.
A pushback of 2 week just does not look like a well enough date to afford them more time. Especially since how “agile” Blizz has shown themselves these days.
Like maybe zombies coming on the 17th.
