Well it’s Xbox and 360 in addition to Xbox One. BC spanning 3 gens is an exclusive feature that they are and should be pushing. Preservation of ones library and games legacy is something all gamers can get behind.
There is demand. That ign survey of most requested PS5 features (bc). A lot of twitter comments, it’s not a niche request. People can buy a new console but still want to revisit games or play ones they haven’t got to. It could be the very simple logic that nobody really wants to go through the effort of hooking up a old console when one box can do it all.
In the end, Xbox does have the power advantage. So Ms will play that card when they see fit.
How many GC and Wii games have I played in the last decade, zero. (WiiU still connected, kids still play MK8 once or twice a year)
How many ps1, ps2, ps3 games have I played in the last 12, 10, 5 years, zero. (PS3 still connected, for blu-ray player)
Preservation of game legacy is great, SotC remake on ps4 and Windwaker on WiiU are amazing highlights. I loved playing Grim Fandango again, Rez Infinite is a masterful fit for VR. Yet BC, I never use it and find it rather pointless for preservation purposes. I rather have remakes or proper remasters, same as scanning the original 35mm movie prints, clean up the scratches in 8K and remix the soundtrack for movies. Even though I can pop the dvd into an upscaling 4K player. (And I never heard anyone say, we need DVD support in next gen players to preserve movie libraries)
However PS5 will have close to 100% backward compatibility too according to Cerny, it's not like it's a xbox exclusive feature.
Can you show us his quote about that?
The latest statement of Sony is that PS5 compatibility is mandatory only for new PS4 games which are submitted for certification beginning 13th July 2020.
Ensuring PS5 compatibility for all the other >4000 PS4 games is "strongly recommended". And it doesn't seem to happen automatically on a system level, but the burden of patching the games is with the game developers (if they still exist).
It's funny people twist Quality Assurance into a bad thing. The PS5 will play all ps4 games, yet it's always possible something doesn't work quite as intended. it won't be any different with XSX. (Why would you need smart delivery otherwise...)
Most games won't need any patches or fixes. It's basically boost mode on ps4 pro. Most games, no issues, yet some might not work completely as intended in boost mode. Plus it's not just whether it will run, different controller, different resolution (text sizes), blurry (low res) hud elements are all part of QA.
