I think the whole retro scene is pretty obviously hitting the bigtime at the moment. Ducati and Triumph come right to mind.
And really, I'm being slightly tongue-in-cheek when I complain about SOHC popularity. I really don't think it's going to amount to much. At the same time, I come from a sport that was absolutely wrecked by popularity and I'd hate to see that happen again.
BTW, I got back from the bookstore (bike is running GREAT!) where I discovered that the newest issue isn't out yet, at least not in my neck of the woods. Can't wait, to tell you the truth.
