So, would a multi SKU PS5 launch be any better than a mid gen upgrade? Say a base PS5 for $399 with mainstream performance then an uber high end $599 PS5 with a near ultra high end performance, that way we would have options right from the beginning which should cater for both the hardcore and mainstream crowd. Of course games will need to be forward compatible at all time but differ in resolution, effects and whatever, you can always do a mid gen upgrade later should the need comes up.
R&D cost shouldn't be affected too much, as long as the uber end SKU is done, the base SKU would just be a cut down version with disabled CUs. Am I missing anything here?
