Bpounds, a lot is regional. They sell those here too, but in the heavily metro Capitol area, there aren't that many places to ride offroad.
But trends come and go. Growing up, there were Harleys (which also includes Indians and the odd one off customs), weird Euro bikes, and UJMs. And dirt bikes, if you happened to live near somewhere to use it.
The leaning back, feet forward, torquey Vs, and relaxed rides aren't going anywhere. It might not look the same (Honda, I'm looking at you), but I believe the ride will be familiar.
