9mmfu has said on the Broadcast Depth thread:
"No, If we did then every patch following it would be slightly off also. better to make just one a bit shorter and keep the regular Updates on schedule."
So it doesn't look likely.
An extension looks unlikely at this point due to a few things. The zombies and Halloween masks are coded to shut off automatically on the 8th so pushing it further back would require a new update which is most likely not something that the team can do. That's what I have on this for the time being, should any additional news come up, we'll let you know.
Good news! We were able to get the Halloween event extended to the 13th of November.
Hmm.. Well i guess it's not that bad..
