It's just speculation from anyone in the media. We've been through it before, and the way more conservative move has always been made. Like Texas and OU and a couple of other schools going to form the PAC 16 and the Big East merging with the rest, the SEC taking Florida State and another to go to 16, and so on.
The grandiose expansion predictions never seem to happen, unless you're involved in the Big East, it's all been pretty moderate.
It's not so much in the media, but people have been leaking it to the media for a while now, including an ex president of the NCAA.

Like Goldeneye says, this is a ways off though.
