In addition to the tomfoolery he had with TI and Jimmy Fallon, Will Arnett also further assured us that there will be a 5th season of Arrested Development on The Tonight Show last night after having revealed some details on The Today Show earlier.

Netflix’s Ted Sarandos was “positive” of a return, but Arnett made doubly sure to tell us all that it will be definitely happening.

However, there’s no telling what the timetable is for shooting or a release, especially considering everyone’s schedules.
