While a flip of KEGL was not unexpected, the choice of Country most certainly was.
DFW already has Country formats on KSCS and KPLX, which have both fallen under Cumulus ownership. The Clear Channel move is obviously intended to damage a business competitor (perhaps killing the format on one of the stations) and to broaden CC's sales appeal amongst its five FM's in the market.
DFW also has Country formats on rimshots KTFW, KHYI, and KFWR nibbling away at the audience, which is why adding "The Bull" was surprising.
Demographic change, particularly in the Houston market, does not favor Country radio. We already have a three-way battle amongst KKBQ, KTHT, and KILT-FM, with KVST and KTWL chomping at the edges. Another competitor would kill one of the existing stations. CC only has three FM's here, and 93.7 would be the only choice for any new Country format. And CC would be going after an outright kill of CBS's KILT-FM. We can all see a big possibility of a flip of KKRW, but a Country format is extremely unlikely...93.7 could very well be the loser in such a battle.
One interesting similarity: If an existing Country format is killed off in either market, SportsTalk on FM might be the likely replacement. Cumulus has the highly successful KTCK in DFW which could move to FM (yes I know about KTDK but it is a rimshot with limited coverage) while CBS could put its successful SportsTalk 610 on 100.3 in Houston. CBS already has a FM SportsTalk format in DFW on KRLD-FM.
