No one's mentioned where--in those cities where
both CBS and Fox have o&os--Nancy Grace will be.
If WTXF carries her in Philadelphia and if
CBS puts a game at 2, KYW could opt out of any morning
game-show feed and simply replace "ATWT" with the new
show; otherwise, your scenario is probably what would happen.
But then again, CBS hasn't said what's going into the 2 PM
slot nor has it said anything about multiple feeds; my hypothetical
is based on the fact that "Let's Make A Deal" is on in the morning
and Dr. Phil at 3 on many of those CBS o&os (just as "Guiding Light"
was on in the morning), so why not the same thing at 2, only with
a different game show and Nancy Grace?
OTOH, if CBS moves "Young And The Restless" to 1 and expands "Bold
And The Beautiful" to an hour at 2 (not likely, given the costs of producing
these soaps), all bets are off; the o&os are sure to take those shows together,
at least in the Eastern time zone, Los Angeles, Chicago, and Dallas.
