Snoxcycle has been around for some time, there's a fellow on the snow bike/Snow Hawk section in Thumpertalk, he says he used to work for him but still stays in contact. Also is talking about the new model you speak of. When the Explorer came to be he had a page on his site dedicated to a new design. it was a painted red trellis design very similar to the Explorer, driven above the track and centered on the rear axle keeping the motorcycle stock swingarm.
The October/November 2006 Dirt Rider article, We test the Snow Bikes, mentioned his upcoming product when they rode the 2Moto pre Radix and Snoxcycle longtrack kits back to back. They used to have a booth at the WSSA snowmobile Expo in Puyallup, and I'm sure other western shows.
Back when Bret Blaser used to talk on here I would bring up Snoxcycle and he would respond, "they don't answer their phone anymore, their no longer".
