A lot of the planned release dates got pushed back a year or two because of covid, so add a year to each date to get closer to when things are probably going to actually come out, I reckon.
I haven’t heard about any plans for PS5 Pro, but all that leaks have said what’s coming out is more like a Slim, since it’s going to be smaller, and not have a built-in disk drive. We’ll see, tho.
