I don't think they will include Georgia, given it has two losses. That means more than likely that OU gets in and OSU gets left out. If UCF wants to get into the discussions, they will have to play some decent teams.
There really needs to be at least an 8 team playoff, you could have the champions of the big 5 conferences and then three at large. One more game is not a big deal and I could argue going for a 16 team playoff even.
