As for Denver, I don't see much chance of KWGN changing networks. KCNC is a CBS o&o, KMGH is owned by a company (McGraw-Hill or whatever it's called now) that affiliated all its stations with ABC, KUSA is owned by Gannett and will stay with NBC, and Tribune would have to put KWGN on the block for that station to have any hope of moving to Fox (and being on Ch. 2, Fox would no doubt love to have it).
The McGraw-Hill stations were bought by Scripps in late 2011, but as you said, and I agree, ABC stays on KMGH for a long time to come. KUSA was previously affiliated with ABC for decades (dating back to its KBTV incarnation), and has been long-dominant in Denver since at least the early '80s. Gannett has a duopoly there as well, with MyTV affiliate KTVD, so no chance of them owning a third station there.
KWGN is more-or-less a heritage Tribune station, so unless the Trib gets an offer they couldn't refuse, I see them staying put.
