Unconfirmed: Fallout 4/Spin-off Teased

The eagle-eyed folks at VideoGamesUncovered have noticed a tweet from Three Dog's voice actor Erik Dellums concerning the return of his Fallout 3 character.
To all my #Fallout3 and #ThreeDog fans: There may be more of the Dog coming! Fingers crossed!

In what? Given the fact that he has apparently been given permission I'd be inclined to think that we're talking about something bigger than a simple media spin-off, possibly something like a next-generation sequel to Fallout 3, still set on the East Coast. Of course, other options such as a spin-off title or a media tie-in are on the table.

It should be noted that we're currently in the process of verifying that the twitter account is not a fake, although at a first look, the chances it's fake are slim at best.

Thanks, VG247.
