If they can't make the PS6 backwards compatible with 4, 5 and 1 and 2 at least, that'll be beyond bonkers. A Raspberry Pi5 can emulate some PS2 games and this would be far more powerful than that. The PS3 I guess is still to difficult for whatever reason for them to get going.

I've never owned an XBox and feel free to correct me if I'm wrong, but I believe they're all backwards compatible? That's the way to do it.
