Brian Griffin is dead and he’s NOT coming back. The dog that’s replacing him on “Family Guy” has already been booked for several upcoming episodes. Former “Sopranos” star Tony Sirico will be voicing Vinnie, after Brian was killed off in Sunday night’s episode. There’s been a lot of wishful speculation that Brian’s death was a one-episode gimmick — and that the dog will come back, but that doesn’t seem likely. Vinnie the Dog has already been voiced for another 6 or so episodes. There’s probably even more to come after that, too. So basically, Brian’s not coming back… at least for a very long time which is probably never… Wah.
