playstation 6 already?
Other than a die shrink or chip reduction or something there’s not much else to do. The designs are basically done.
So all hardware work would currently be focused on the PS6. At least for the home console line.
But for their hardware engineers they’re likely done and moved on.
However, most games nowadays can't even take full advantage of PS 5 and XBox Series X, so it is quite questionable what they will do with next generation.
Switch might be oldie hardware, however it clearly shows how well a console can sell when more attention is given to gameplay than polygons per second.
