This has long been a problem in road biking, where carbon-copy carbon frames are often lauded for their lateral stiffness and vertical compliance. Or was it the other way around? BikesnobNYC would know better than I.
Personally, I get more suspicious about a product the more trademarked names and processes that go into it. The more complex a company makes something out to be, the more I suspect that they're just blowing smoke. Multi-Zone Tread Design? Ultimate Traction Control? PermaTread Design? Who comes up with this stuff? Unless it's intended as some sort of elaborate joke—and I don't think it is—isn't it a little too much? Can you read through that entire overblown press release without laughing? I can't.
Somehow I don't seem to recall the Comp III needing this sort of hardcore sales pitch, and it seemed to do OK. Be interesting to see whether the Power Block sticks around half as long. My guess is no.
