The Ketchum guy was back on Finebaum and seems to think it is a done deal. He also owns(?) the Orangebloods.com site and works at an ESPN radio station in Austin. He said a Big 12 North school AD had told him their school had been saved.
Texas still the big dog and would have the most revenue, especially with rights to launch its own network, as all schools could, but Texas would expect to make the most money from that.
And, Gene Stallings indicated today that the league might have been saved. Seems to be a done deal unless if falls through at the last minute, or unless this is some of the most inaccurate reporting ever.
You might want to follow Chip Brown on Twitter; he's gives pretty up to date info on what's going on.

ESPN is now picking this up after staying with the PAC 10 story until a few minutes ago:
