Those aren't optimized they're "Featured". It just went from 59 to 52, those 7 apps went to they're appropriate sections. I don't believe there is an optimized for tablets section for tablets. Would be nice.
As a dev, I can tell you that they're being worked on. Also, do searches in the Market for things like Xoom or Honeycomb, because what you're seeing, as mentioned already, are not all of the Honeycomb-optimized apps. I have two Honeycomb-only apps, and neither are in that list.
