You might have noticed a fair amount of media coverage on the PS4 hit last night that covers some of the upcoming features for the PlayStation 4 (including Havoc mode). Have a look at Polygon, IGN, Gamesbeat and others for some of those details. Part of the reason for our silence was to not undercut the media coverage that we knew was coming as a result of our media tours done in the US and Europe about two weeks ago.
As our first closed beta update nears release (I hesitate to give a date as there's a couple things we still need to fix before it's ready, we are slightly behind our originally planned schedule), we will get some more PS4 goodness to you. This next update is sizable relative to the first closed beta version and surely our community team will provide additional details once everything is locked and loaded. We have a whole separate team at Iron Galaxy assisting Yager with the PS4 version, so while it's getting updates, it's still going to be in closed beta for a good while yet as more and more systems/features and content come online.
