First off, Rob is semi-retired and I don't think he's interested in releasing any new products. Secondly, the FDA regs prohibit new products that weren't on the market before 8/8/16. Sure, the Chinese manufacturers and sellers don't care, but a US-based business kinda has to. Rob did make a regulated mod at one point, the VV REO Grand. That was before DNA boards even existed. But those mods were a headache from a service standpoint. Rob's philosophy has been that a mod should last a lifetime and be readily fixable when it fails, which is rather difficult when the supplier for the the board stopped making them. Then there's also the problem that juice and electronics don't mix, and many users aren't as fastidious about keeping the innards of their squonk mods as dry mod with a regulator in it should be.
