I don’t see why console companies don’t launch with the “slim model” to begin with. They are showing us it’s possible, so why not start with that? I don’t think it would reduce initial sales any.,(reply>), Refinement, technological improvement, and market research all take time and often depend on the product already existing in user's hands. That all goes into creating a slim version. Sure they could have spent more time figuring out how to refine it and make it smaller without releasing it, but then it would still release close to the time the slim version releases anyway and they wouldn't be making any money in the mean time and be missing out on a whole lot of market research for future input.,(reply>), I see it as they didn't have any "idea" or they weren't ready to mass produce a smaller die version of the PS5. I imagine they make the regular chip and then for the next few years figure out how to slim it down.
