On Friday at PAX 2010, Gearbox and Take 2 announced that the biggest vaporware title since Team Fortress 2 was coming back to life.
This time was different though from all the other 'announcements' that have come and gone in this now decade old saga. They brought along a playable demo of DNF for everyone to try out.

Here are some links to IGNs coverage of the announcement as well as some (poor) videos of people getting their hands on DNF. They are using 360 controllers but it is the PC version of the demo.
