The Big 12 has its 2012 schedule ready to go, featuring new members TCU and West Virginia.
A full schedule has been given to the league's TV partners, per its contracts with those networks. But the schedule has not been released publicly yet. That is supposed to come "in the near future." The ongoing court battles between West Virginia and the Big East might have something to do with that.
The Big East has not given a time frame for releasing its 2012 schedule.
