Not basketball specific (more relevant to football, really), but ESPN.com has an article discussing the financial impact on the big schools involved in realignment. From the discussion of A&M:
So, thanks to football, total ticket sales revenue has actually increased despite the decline in men's basketball.

Ticket sales revenue -- about $37 million for all sports combined -- had been steadily increasing since 2008, and average sales for the first two years in the SEC were 6 percent higher than the last two years in the Big 12.
The bump in conference revenue was more substantial: Last year, the SEC gave Texas A&M about $21 million, which is an increase of about 72 percent from the $12.2 million Texas A&M received from the Big 12 in 2010-11. (The Big 12's tax returns show it gave the school just $3.8 million in its last year in the conference. It withheld $12 million, prompting the university to give the athletic department a loan, which is being paid back $1.5 million each year.)
Getting $21 million from the SEC might not seem like a big coup, considering the Big 12's payouts now average $21 million, and it isn't right now. But that doesn't factor in the future revenue potential of the just-launched SEC Network by ESPN. Much like the other schools that moved from one major conference to another, the big payoff is to come. Some estimates show that in only the third year of the SEC Network, schools could see payouts of $40 million.
So, thanks to football, total ticket sales revenue has actually increased despite the decline in men's basketball.
