Everyone assuming this is the big one that ends it all. I think that is premature. The ACC will be around for awhile. It may need to expand. The remnants of the Big 12 and PAC need to figure out how to best combine and create the best media package. Those left out of that, will likely connect with the MWC (I can see Oregon State and Washington State being left out, maybe BYU too....plus the schools just added are in a tough spot).
Will they be financially disadvantaged? Yes. But the reality is that cable TV itself is doomed, and so these giant media deals won't last much longer. The USC and UCLA move tracks with national recognition being more important than local markets in a post cable, streaming world. The ACC has great, growing local markets, much better than the B1G or most of the SEC. When "the big one" comes, the stragglers in the SEC and B1G will be cast aside too, and the stronger programs in the other conferences will get an in. We haven't seen that yet. When Northwestern, Rutgers, Vandy and Mississippi State get the boot, then I'll believe the split is coming.
