Did Transtech make it to the prototype stage?

For those who don´t know, Transtech was supposed to be a followup to Beast Machines. The series would have continued along the Beast/Vehicle/Robot theme. However, the idea was scrapped, and replaced with Armada (and RiD as a filler). So there, you´re all caught up. For years, we´ve been told that the line was cancelled before any prototypes were even made. With no evidence to the contrary, this generally believed by the fandom at large. But now, we have reason to believe that at least some of the figures made it to the prototype stages. The Energon Pub members are sure to have plenty to say about this, why not check it out?
