It's now pretty definite that it'll air tomorrow night. I was in the green room for the show tonight, as I have been all week, and everyone with the show told me that they saw the segment in rehearsal today, and that they thought it was really good.
I still don't know if I'll be on with it tomorrow night. They've got reservations for me on two flights to Minneapolis, one departing LAX at 2 PM or so, one departing at 11:50 PM. Either way, I'll get to be home in time to do laundry, re-pack, and head back to Minneapolis for CONvergence - though I may spend a good part of Friday napping after vakkotaur and I get there.
In any event, it's definite enough that the segment will air - with or without me - that I'm going to tell everyone to set their VCRs. I hope it's really as good as the folks with the show say it is.
