In news that comes as a surprise to no one at all, HBO has renewed True Blood for a fourth season.
The series full of blood-sucking deviants is in the midst of its third season at the time of this writing, but HBO believes strongly enough in the show to already greenlight another season. Season 4 will be comprised of twelve episodes, just as the current season is.
THR reports that the show’s Season 3 premiere was up 38% in viewers over Season 2’s debut. Season 4 will debut Summer 2011.
