popped up on RockPaperShotgun two days ago. Basically, it's an intreview with the guy who's making End of the Line. While it's kind of a standard intreview (To me, anyways), there's something near the end that might be of interest to you guys.
RPS: Valve have spoken to you about the possibility of End of the Line being an official update, with supporting content. What would that look like? New maps or modes around the short?
McVinnie: This is the question we’re asking ourselves and trying to figure out on a daily basis. We’re currently experimenting with prototypes on the side of the video production and keeping an eye on the steam workshop to see what people are making.
So basically, we might be seeing an update around the short soon.
EDIT 11/24/13 - Icehat brought up this Reddit Thread
made a person claiming to have played with McVinnie. According to what he's saying, not only is this update now confirmed, but also going to be focused on weapons and maps.
This going to be rather interesting...
