AccordPazerValve didn't directly give us info on when the update would be out. They just listened to feedback from us for the most part.
So not exactly a joke, just a tease for something that could be totally wrong. I (incorrectly) assumed that "joke" was the correct way to describe something like that. See https://twitter.com/danekevincook/status/904040139369865216. Sorry.
Other potentially interesting things:
TF team is the same size it was in January
The move to the new building is being delayed due to issues with permits or something. New building will be roughly 2x the square feet.
Valve knows the community is upset with the long wait. They've decided that quality is the most important thing, they really don't want to release a broken/bad update.
Valve knows sniper can be a huge pain in the hands of a good player. They have 2 good snipers on their team who will sometimes get kicked from pubs for cheating.
