Kotaku Video is here: http://www.gamesas.com/topic/1379724-june-6-kotaku-interview-with-john-carmack/
CVG link was removed because it didn't had part3 of the video but it were also the same exact videos as on pcgamer.
Update:
Some articles in text: http://www.theverge.com/gaming/2012/6/7/3068819/john-carmack
http://www.t3.com/news/john-carmack-unveils-virtual-reality-gaming-headset
I am contacting and trying to get videos in some original articles without vids.
Update 2:
I've just spoken with Eurogamer and they've said there was no video unfortunately, only audio, but the quality is very bad because of the noise around E3, but they said they'll do something soon that goes deeper, so we might get even more info, stay tooned.
UPDATE: Uncut Eurgamer Interview now online:
