Pearl Hy-road? I thought the "HY" in Hy-road came from the fact that it was a HYbrid coverstock to begin with. To have a HY-road that is NOT a HYbrid just seems odd.
As for the Marvel S, I can see that. The Marvel line was successful, but the solid left something to be desired by many, so why not try a new solid cover in that line, even if only to give it to those who want a full lineup of one model?
