I do not think the lite version will have a major impact on sales after it's first launch week. I will wait on buying one personally as I don't feel confident about the quality of the analog sticks. I have the OG and I have already replaced the Joycon two times so I will wait for a youtuber to open the console
Regardless, Sony is making so much profit on hardware sales at the moment and with the psvr market and accessories hitting new strides, I just don't see why they would lower the price anytime soon.
It is basically a $100 price cut. Baseline will be raised for the rest of the year and a good time after, not just the first week
