If there was any doubt that ABC affiliate KESQ is Coachella Valley's HD leader (was there any doubt? We're not sure), let it be erased, as it kicked off HD newscasts April 20. Asserting itself as the only HD news station in the Palm Springs, California market, we're hard pressed to see why you'd watch anything else. KPSP, KMIR and KDFX, the gauntlet has been thrown down, it's your move.
