While the UC Regents has to at least be nervous at the moment, my completely uniformed opinion is UCLA goes to the Big 10 without too many problems.

My equally completely uniformed opinion agrees with you. However, I do think there is a non-zero chance we are both wrong. I am beginning to wonder if some UCLA staff and alums aren't happy about this and are prodding/working the Regents. The litigation risk was always there and nobody said anything. Why now after supposedly all is said and done?

The reporting on this is all over the place, so one has to take what they read with much salt - particularly as I have read several incompatible stories. 
With that caveat, my impression from several articles is that the UC President (former president of Ohio State) knew about the move and decided that the various campuses have autonomy to do what they wish on athletics without consulting the Board of Regents. Now, the Board of Regents seems to be thinking otherwise. While university boards don't usually buck their presidents, it does happen - particularly on political hot potatoes.

Slightly OT, but I was struck by the number of UC regents who didn't attend one of the UC schools.

It is a political position.  Where you went to college is unimportant.  What is important is your connection to the Governor, with the primary qualifying trait being an effective campaign fund raiser.
