When ESPN steps up with more cash for the ACC, which I think they will, FSU will sit tight.
I also think the era of SEC dominance of college football is nearing an end. With the dollars as large as they are, one of two things will happen with the rampant cheating: Either the other 4 major conferences will drop the hammer on the SEC or they will decide to cheat too, and just change the rules so it is not cheating. Does anyone think the 4 other majors will just hand over $100MM a year in performance money from the playoff to the SEC when everyone knows the SEC is paying their players? For $5MM to a conference per year (the bonus for getting a second team in the BCS), the other leagues will value their integrity. At $100MM a year, something has to give.
In addition, any selection committee is going to take a look at SEC out of conference schedules and start punishing teams for not going on the road. There is a barely perceptible home advantage in about half the BCS computer rankings. If the SEC was run through a RPI type formula with a heavier home field advantage adjuster, most of the last few years the rankings would quite a bit different.
FSU wants to be associating with the ACC universities, and as long as ESPN shows them the Quan, which I think ESPN will, FSU will be in the ACC for the foreseeable future.
