toraider I think it is a possibility - if LIV starts signing some of the up and coming players out of college and the feeder tours. Otherwise, those players will continue to feed the current system while the LIV tour ages out of relevancy. If the players that have moved over already have a significantly negative impact on TV ratings next year then sponsors for the PGA Tour will want to start reducing their contracts while the Saudis have the ability to wait things out if they really want to.
I'm inclined to think they won't ever merge right now, but it all depends on how much money LIV is willing to sink in order to win.
