Let's start this off with price concerns. While Sony hasn't revealed a price officially, there is enough chatter from insiders to get a clear picture of the manufacturing costs for PS5. An insider claims that Sony is struggling to keep the price of the new system down and that the current development costs for a PS5 comes to a total of 450 dollars.
However, in comparison to the PS4, the price tag for the final product would come closer to 500 dollars than 450. The final costs for the PS4 came in at about 381 dollars per unit with final pricing being 400 dollars.
One would assume the same process is happening for the PS5, but because 470 dollars is anything but attractive marketing-wise Sony would probably up the price to 499 dollars.
The biggest concern in all of this is that the manufacturing costs are not the final estimates for how much the console is going to cost. There are many other factors that need to be included which is likely gonna bump up the price even further from that initial 450 dollars.
Add the unknown factor of possible delays due to coronavirus and the costs might increase even further.
