NBC revealed a big chunk of its primetime plans for next TV season this morning, announcing six new dramas, four comedies, and four renewed series. But it left a lot of questions open, too — including the fate of Chuck and Law and Order and when all of these shows will fit on the new primetime schedule.

Those answers are supposed to come May 19 — the same week the rest of the networks will announce their schedules. But for now, here's what we know: The four new dramas are Parenthood, based on the feature film of the same name; Trauma, a fast-paced medical show; Mercy, another medical show revolving around the lives of nurses; and Day One, about the aftermath of a global catastrophe. The comedies are Community, about a band of misfits at a community college, and 100 Questions, about a young woman looking for love online.

Returning for sure next season are Heroes, Parks and Recreation, Southland, and Saturday Night Live Weekend Update Thursday, which aired a few special episodes before last Fall's presidential election and will air six more times this Fall. Despite reports of a renewal over the weekend, no decision was announced about Medium. The network previously renewed The Office, 30 Rock, The Biggest Loser, The Celebrity Apprentice, Law and Order: Special Victims Unit, and Friday Night Lights and had announced the new reality series The Marriage Ref, Breakthrough with Tony Robbins, and Who Do You Think You Are?
