Sean Hayes -- who pretty much disappeared from TV after "Will & Grace" -- five years ago! -- is coming back. Bob Greenblatt, NBC Entertainment boss, said at the Television Critics Association meeting that he signed a development deal with him that'll yield a whole bunch of stuff -- scripted series and even a reality show with celebs -- but foremost a headlining series. Arrival date: Next season.
And in other development/star news:
-- Dick Wolf is working on a new pilot about firemen; no delivery date, but Dick's post "Law & Order" life is moving on.
--Mariska Hargitay will appear in every episode of "SVU" next season. There had been rumors that she'd be cutting back or eventually leaving. (BG did not address the future beyond next season and, as you know, Chris Meloni is gone.)
-- There will be more actors hired on "The Office." Yes, actors, plural. BG said adjustments will be made for James Spader's character, but that he did attend a couple of table reads and everything seems fine.
-- A Michael Buble variety special is being developed, too.
