The "9th gen" won't happen as you expect. The original xbo/ps4 will be phased out, neo/scorpio will be the new basic model and a neo2/scorpio2 will be more powerful machines available at the same time with the same games. Incremental upgrades is the future, no more traditional generations.
Multiple Devices available at the same time, each device supported, not until the next more powerful device launches, but until the device after that launches.
