More value-oriented versions of these processors will almost certainly be coming in the first-quarter, and I doubt they will be "limited edition" releases, but rather the normal versions of the processors that most people will be buying. AMD just decided to put the higher-priced variants out first, since they knew those had been a much tougher sell in prior generations, when released alongside models offering nearly the same level of performance for significantly less. Since initial production was going to be limited, it makes sense for them to sell chips as higher-margin parts initially, especially since they currently hold a performance edge over Intel. They obviously won't be able to do that if Intel increases competition with their Rocket Lake lineup though, so there will undoubtedly be better-value parts on the market by then.
There has already been rumors that a 5600 (non-X) will be released for around $220 or so, and I would expect an 8-core for around $350, both probably with included stock coolers. It wouldn't be surprising to see these announced during their CES presentation in January, though there is also the possibility that they might not come until closer to the Rocket Lake launch. There are obviously some big price gaps in AMD's current lineup that need to be filled though, and based on recent 3600 and 3700X pricing and availability, I would expect that they have either ended or significantly cut down Zen 2 chiplet production, and are focused on Zen 3 now. So, I would expect Zen 3 successors to those parts to be coming within the next couple months or so.
It's nonsensical to base pricing on power draw. Their redesign of the architecture improved efficiency, and not much performance would be gained by pushing power levels higher. And while the 3600X may have been paired with a "95 watt" stock cooler, its actual power draw was very similar to that of the 3600. I would have preferred to see them keep the Spire cooler given the higher price point, and would have also preferred to see somewhat lower launch pricing, but practically speaking, they sold out either way, meaning they arguably made the right business decision, at least for these early-adopter parts, which seem to be aimed more at those who don't care quite as much about getting the most value for their money.
