I plan on driving up for it. I'm still waiting out the tickets though and figuring out the best way to get a cheaper single ticket in the lower sections. I figure I might as well make a day out of it and stay for the 2nd session too.
Here is a seating chart:

I suggest you print this out and bring it with you if you are shopping for tickets in downtown OKC.
Based on my experience, single tickets usually can be found outside an arena for a reasonable price. Of course there are no guarantees, but the fact that there are that more than 1,000 for sale on Stubhub may indicate that there will be a lot of tickets for sale tomorrow.
The other three teams in Session 1 (VCU, Oregon State, CSU Bakersfield) will not bring many fans since they are coming from so far away. Sooner fans may surprise me by showing up in large numbers, but I think it will be a "buyers market" for tickets outside the arena. Just be patient and persistent.
Note that teams playing in session 2 (A&M, Green Bay, UT, UNI) do not receive tickets to session 1. There are almost 1,700 tickets to session 2 on Stubhub. Those tickets will be cheap come Friday evening outside the arena.
Also, the WILL CALL windows at the arena open at 11am. Some visiting fans may have one more ticket than they need, so that may be a good place to check out. These "team tickets" should all be lower level tickets.
