A tweet from shinobi602 answers a question about whether Bethesda will unveil Fallout 4 at this year's E3 with a vague affirmative, saying: "I would say that's a safe assumption." This has been the subject of speculation since Bethesda recently announced its first-ever E3 conference. As noted on PSU, shinobi602 is known to be the source of accurate insider information in the past, so while this is completely unconfirmed., it is being taken pretty seriously. When asked to rate how likely this is to happen on a scale of one to 10, he replied "11."
