That would be stupid. I can't believe they so worried about the X and people moving over to PC ? Head start is good but that would be stupid IMHO. They should release the PS4 Pro slim this year with official price cut and have as many bundles and sell as much as they can. May be in end of 2019 Pro slim at 300$ and PS5 500$ ? can co exist. But I am not sure native 4K is enough for 500$. 2020 I think most people would buy if they have exclusives taking advantage of PS5 specs.
