NBC has been leaking like a sieve for weeks, so other than a few on-the-bubble cancellations, there aren't any huge surprises in their official upfront announcement. The big change is that they're doing two official seasons. A lot of the networks have been doing this unofficially, but NBC seems to be one of the few that is putting a label on it.Returning: Heroes, The Biggest Loser, Law & Order: SVU, Saturday Night Live, SNL: Weekend Update Thursday, Parks and Recreation, The Office, Law & Order, Southland, Dateline NBC
Returning mid-season: Chuck, 30 Rock, The Celebrity Apprentice
Gone: Life, Medium, My Name is Earl, Kath & Kim, Kings, Knight Rider
New: Trauma, The Jay Leno Show, Parenthood, Community.
New for mid-season: Day One, 100 Questions, Mercy, The Marriage Ref
Not reflected on the schedule, but will be returning in the summer: America's Got Talent, Friday Night Lights (which will once again be aired first on Direct TV).
