My take on what the prices should be:
Switch Lite: $180
Switch OLED: $300
I don't really think it's happening, at least not this year. I always thought Nintendo was going to wait a quarter of OLED in the market, see how much it can sell and then decide if they will price cut Switch family or not
I believe N planned to remove the base model anyway and replace it with the OLED for $300. They might have accelerated their plans to get preorders up and curb the Valve tablet.
