i don't think the cafe thing is going away anytime soon...i get more and more people asking me about building them as time goes on.....
IMO Carpy is popular because he has built some great bikes, has a variety of styles, and more importantly a good website that is easy to find. Lets be honest, this bike might not be the best example of a cafe, but it is better than a large percent of the bikes I see around Denver that people are trying to call cafe's....just search craigs list for cafe...its really silly what some people are doing right now...putting some clubman's and pod filters on a bike and calling it a cafe is just silly...
Moreover, emulation is a high form a flattery...even when it falls short a little...to the general public this bike would be something new and different, even if we know exactly where it came from.....
As a builder and someone who really like old jap bikes, I hope we get more people building/wanting bikes like this and increasing interest in old metric bikes in general...it may increase the price we see for buying project bikes, but it will also raise the price of bikes we build.....sure there will be some flops but there will also be some really new and interesting builds to admire...
