Fallout 4 Tease?

The Twitter feed for Erik Todd Dellums has clues from the voice actor that seem to reveal plans for Fallout 4 or some other future installment in the Fallout post-apocalyptic RPG series. This tweet suggests we can expect a return of Three Dog, his DJ character from the game: "To all my #Fallout3 and #ThreeDog fans: There may be more of the Dog coming! Fingers crossed!" A subsequent tweet says he has been authorized to blab like this: "How was that for a tease! I was given permission to release that tease, so fingers crossed." Thanks VGU via No Mutants Allowed.
