DW says that the demand was so high for these new pedals that they may see light of day sometime around June.
originally slated for next year release, so I am not putting too much into seeing them this summer. It took me 5 months just to get my 9000 hihat.

The new Gatzen pedal is based on Bow Flex technology, no springs and the tension and angle of the footboard is controlled by sliding a plate at the base of the footboard and the heel plate ever so slightly.
