There has been rumours floating around that Fallout 4 would be announced at the Spike TV Video Game Awards (VGX) this Saturday. Fairly loose rumours. You can disregard these now as Bethesda PR and marking executive Pete Hines took to Twitter to clear things up.
"No, folks. I am not going to VGX. Bethesda is not showing/talking about anything at VGX. Just some PR meetings in LA. Take deep breaths."
Fingers crossed for an E3 reveal then, eh?
