Veronica Mars is still clinging to life. Despite reports this morning that the show has been canceled, Rob Thomas just assured me via e-mail that there's "nothing definitive." That jives with what I told you in Ask Ausiello: It's possible CW head Dawn Ostroff is delaying a final verdict on VM until after Thursday's upfront. One encouraging sign: Sources say Rob has passed on CBS' offer to come aboard its new musical mystery drama Viva Laughlin as an executive producer. (Rob declined to comment on anything Viva-related.) Anyone wanna guess what the first question out of my mouth will be at tomorrow's CW press conference? C'mon, give it a shot.
