PS5 will also feature better Wi-Fi, Bluetooth and USB versions than all the other consoles, which will help in several ways the consomers not only with the new PS5 games, but also with the BC ones.
This also will not only help the new PS5, but also BC games, because they will allow you to use external USB storage to store or copy PS4+PSVR in addition to their save data.
You'll be able to copy them from a PS4 to PS5 via wifi too, or to play online BC via a better wifi than in PS4 or PS5.
Having 3 USB-A available ports also allowed them to make the PS4 accesories like driving wheels, arcade sticks or headsets (USB or via 3.5 jack) compatible to use them on PS5.
Sony announced they were increasing the price of their games. Microsoft haven't actually responded, but, when they do it will be in response to Sony. So it's Sony led.
Well, we'll need to wait for a while to know it, because seems that the first next gen only AAA (I think outside NBA2K21 these are the ones who increased their prices from Gearbox and Sony) from MS won't be released soon.
