Per McMurphy (no nothing on UT's exit date):
"Cincinnati, Houston and UCF are negotiating a settlement in the “$17 million to $20 million range,” which would allow the schools to exit the American Athletic Conference early and officially join the Big 12 on July 1, 2023, sources told Action Network.
The completion of that deal would then allow the six Conference USA schools — Charlotte, FAU, North Texas, Rice, UAB and UTSA — to join the AAC on July 1, 2023....
Multiple sources said they are “fully confident” that a settlement will be reached this month by UC, UH, UCF and the AAC.
The addition of BYU, Cincinnati, Houston and UCF will give the Big 12 14 members next season, including Oklahoma and Texas, which will be leaving the Big 12 for the SEC in 2025 — unless they negotiate an early exit....
The C-USA schools moving to the American must forego two years of conference revenue to the league, sources said. That amount could range from $1.5 million to $3 million per school, depending on whether College Football Playoff and NCAA basketball tournament revenue is ultimately determined as revenue provided by the league. The exact buyout remains undecided, sources said.
Besides those six schools leaving to the American, Conference USA members Marshall, Old Dominion and Southern Miss, along with FCS member James Madison, will begin play in the Sun Belt this season. The C-USA schools negotiated a buyout with the league in the “neighborhood of $1.75 million” in addition to forfeiting one year of conference revenue, sources said."
