Let's presume the IJN has altered their sailing schedules for the three prong forces. Ozawa still lures Halsey off to the north, Halsey still taking the carriers and battle line with him. Nishimura and Kurita coordinate better, with the two forces coming into the gulf at about the same time, maybe just before sunrise when IJN visual sighting come into play, and it's not a one sided radar fest. This time, US scouting has missed the two IJN prongs, perhaps looking elsewhere or looking at the wrong time. Musashi survives in fighting trim. Kurita's force descends upon the beachheads (ignoring the Taffy's) at the same time Oldendorf begins his fight with Nishimura. Oldendorf should still knock out the southern force, but while occupied with that force, the fox would be well and truly among the chickens with the beaches at Tacloban. The IJN cruisers screen against the Taffy's. A reversal? A setback? Delaying the inevitable?
