FWIW, my tickets arrived today (NU allotment). I ordered through a friend with a decent number of priority points, so we got our requests in before the pre-general sales deadline. Our seats ended up being two full sections away our requested section. That's a bummer because the seats are worse than we'd hoped for, but I guess it suggests that sales aren't too bad. I'd also estimate that about half of the people I know who will be at the game are purchasing through the secondary market.
6-10k NU fans still seems like a safe bet, and I'd guess it'll be in the mid to high end of that range. Anyone else have any info?
