BC would be nice, especially for Nintendo's follow-up to the Switch. The Game Boy, DS, and 3DS lines were always backward compatible to the previous generation, with the GBA being backward compatible all the way back to original GB. Switch had to start fresh because its hardware was radically different from the 3DS.

If PS5 were to perhaps be clearly less powerful than Scarlett, PS1-PS4 BC would help bring in gamers for other reasons. Reasons that would no longer be an advantage for Scarlett.

Would think a solution to this would be to allow the ps5 to use the DS4 but then you possibly undercut the ability to sell ps5 controllers, the flip side of that is looking at the Switch, you can use almost every controller with that machine if you got the adapter for it all the way back to use old GC pads for 8 player smash bros, could be a way to allow full backwards BC and the only real cost would be hardware sales to people who love collecting hardware anyway so they'll likely buy the DS5Pro and then be happy to have that for ps5 games and use the DS4 for the titles which require it.

It would be a nice thing to have, fully backward compatibility.... I'd trade in my systems in a heartbeat and go all in on ps5 and xbox.....2..... or whatever the hell theyll end up calling it.

All systems should be compatible with NES, Genesis, and Atari 2600.

Add colecovision and LCD handheld games. Anything else would be unacceptable. At launch of course.
