The Trident HG3 speakers were first announced at the '09 AES. Since then many audio pros have been waiting anxiously for these speakers to hit the market. I've heard through the grapevine that they will be released shortly.
"Legendary speaker designer Harvey Gerst worked with noted amp designer Russ Allee to create the new HG3 powered close-field monitors for Trident Audio Developments. The HG3 speakers combine a midrange and HF driver in a separate swiveling enclosure set into a ported subwoofer cabinet, with the swiveling action greatly reducing diffraction distortion while letting users adjust directionality for improved imaging. Three sets of inputs allow for balanced (XLR and TRS) and unbalanced (TS and RCA) connections." - George Peterson
Here's a video clip with Mr. Gerst explaining the design of the HG3 in more detail:
