It was announced this morning during the Keynote address that LEGO has created a 3rd party Developer Program that will feature HiTechnic sensors and devices available for sale at the LEGO Shop-at-Home and on HiTechnic's website. More information as I can get it... Brian Davis is at BrickFest and may be able to provide more details later.
Video of the announcement here.
Congrats to HiTechnic... I'm looking forward to some great add-ons!
