In an interview with the German colleagues by GameStar, Todd Howard of Bethesda spent a minute of his time to talk about the next project in which they are working, declaring that when presented will remain all open-mouthed, besides making a small hint of false rumor circulated about Fallout 4. This hint bar the announcement of the fourth installment of the series? And if it were a new universe, maybe with the structure of an MMO? You can retrieve the extract of video interview at this address , even if it is in English and German language subtitles.

Update : the original interview no mention of E3, but Howard explains that the game is kept secret for now to show when it is ready. So you were talking about a revelation of E3.
