Now The Big East And The Big 12 Can't Agree On When West Virginia Is Leaving

There's this:

The Big East requires a 27-month window of notification before teams may leave the league.

In other words, no earlier than the 2014-15 school year.

And then there's that:

The Mountaineers will begin competing in the Big 12 beginning with the 2012-13 athletic season.

Maybe the SEC already has a press release ready to sort it all out.
