I got this confirmed from a source at Google (to remain anonymous) that Honeycomb will likely work just fine on all the cheaper tablets, such as the ARM Cortex-A8 ones like Archos and even the super cheap ones with Rockchip ARM9 or Telechips ARM11 processors. We’re all set for disruptive Android Tablet future with no need to be member of a “high-end special club” to get Honeycomb and especially to be allowed the Google Marketplace and all Google Apps. Google are to update the compatibility guidelines for devices to be Google Marketplace compatible and they “simply” add more filters to prevent consumer confusion.
I’ll try to get this confirmed and explained on video by some Google representatives during the Mobile World Congress.
