We are saying the same thing... just calling it different names.
What you call legs, I call price.
If sony drops the PS4 to $149 this year, be rest assured it would sell another 20M unit even after the PS5 launches. At the launch of the PS2, the PS1 cost under $100. The PS2 cost $149 when the $599 PS3 launched.
But my main argument is that the PS4 doesn't even need to have legs. Sony needs to get the PS5 out and have a SKU be $399, and get the price of that SKU down to $199 as soon as possible. You want as many people on the new platform buying their games directly from you with no used game market insight and not people still buying your previous console. And I can see why they are stubbornly leaving the PS4 price at $299. They may want to create a situation where you should buy a $399 PS5 instead of a $299 PS4pro slim and a discontinued PS4 slim.
And I don't feel the investment required to make a PS4 super slim and a PS4 pro slim is necessary (even though I suspect sony may still do it).That's at least $300M in R&D and retooling. That kinda money would have been better put towards subsidizing the cost of the PS5 DE and bring it in at $349 instead lol. Or hell towards some other first-party projects.
Call me crazy, but I am of the mind that if your previous console is still doing very well when the new console comes out, then something is wrong and you have a big problem.
There is no even small chance for Sony droping PS4 price to 149$ this year. In 2013 some websites reported that PS4 manufactering cost is 381$. After so many years it still wont be much lover than half of the intial manufactering cost (about 190$ now) They really dont need selling PS4 at lost now.
Also the PS5 wont get the 199$ price point for a very long time, just look after PS4 - the suggested price is now 299,99MSRP, so hoping PS5 will get a 199$ in the near future is just "best wishes"
And comparing PS1 or PS2 prices (at the end of their lifetime) to PS4 situation is just wrong. The market and technology situation is so much different now than back then.
