I doubt it also. She has too much baggage. I'd guess WABC, WPVI and WTVD, the east coast ABC O&Os will move Rachael Ray to 4, and then ABC Domestic will try to find/groom someone else for themselves with a launch at 10am, with the hope of it doing well and it moving to 4pm. Hopefully ABC's idea isn't to supersize The View (something NBC would do...just supersize something already existing when ideas run out).
The Hearst stations that have Oprah might also be having Ellen, so might move Ellen or Dr.Phil, depending on what they have to 4pm.
Allbritton WJLA, and Cox WSB might be on its own, expanding its news or finding syndicated.
I'm not sure what ABC would do on the west coast, but the presssure is generally more for WABC. In Chicago, WLS could pick up R&K.
