Boise State has been set to join the Big East for football-only starting in 2013, but they were having cold feet since the WAC was on life support. However, San Diego State intervened to help to try to get Boise State in the Big West for their non-football sports, and something must have helped since the Big West called Boise State to discuss future membership options.
The WAC is still where Boise State would want to have their non-football sports, but now that they have options with the Bg West Boise State is moving forward to join the Big East in 2013. CBS Sports Brett McMurphy (of course he has the story) is reporting that Boise State will indeed leave the Mountain West for the Big East:
Boise State, after strongly considering remaining in the Mountain West, will continue with its plans to join the Big East as a football-only member in 2013, industry sources told CBSSports.com.
[...]
Sources told CBSSports.com the Broncos were considering remaining in the Mountain West for several reasons: the uncertainty about the Big East's future membership, the difficulty of securing a home for the Broncos' Olympic sports, the elimination of the BCS AQ conferences in 2014 and also a very real concern that their revenue as a Big East member would be substantially lower than initially projected.
It looks like Boise State is on their way out of the Mountain West even though there is uncertainty in Big East membership with Louisville and Connecticut openly wanting to leave the Big East.
