So yeah I may as well post this here.
The Duke reveal is Gearbox's Duke3D re-release coming with a new episode, new lines, weapons etc.
I knew about this months in advance but it's nice to get confirmation.

Countdown sites are pretty much irrelevant now since people are always able to access the content one way or another.
Also they missed Duke3D's 20th Anniversary by a few months as well as Duke's 25th.
But what's really interesting is Gearbox is putting a hell of a lot of effort into hyping this thing, the countdown site, making a Twitter page for Duke himself and having Duke send hate tweets to Randy Pitchford as well as firing up the Duke Facebook page for the first time since 2012.
It's not like this is gonna be a huge seller, pretty much every self respecting FPS fan has either played or already owns Duke3D.
I think it's a solid bet that a brand new Duke game is not too far off.
