They also said they'd release the Quake Con footage after Gamescon. There was a rumor that would be today, but you know how rumors are.
There is Pax in Seattle. I do not know if Bethesda will be there
The rumor was here on the boards. Grain of salt.
And do a check on youtube for it, you'll find a plethora of people who were at Quakecon, Gamescon saying it.
I don't keep sources on hand.
Well, Courtenay Taylor (Female voice) did tweet https://twitter.com/courtenaytaylor/status/631526618683412480 yesterday morning. So hopefully we'll see something soon?
Took a look around, seems to be people thinking and guessing that it will, but no actual confirmation. Closest thing to that was the "Please stand by" tweet from the Fallout Facebook page when someone asked if the QC footage would be uploaded.
