Is Steampunk ready to hit big?

There seem to have been several times in the past where steampunk could have taken off but there only seemed to be a blip in the mainstream. But I am wondering if maybe things are getting closer to a next big thing bump.

Or is there kind of a set of hard core followers and some casual fans that come and go and that is as far as things will go?

…I don’t know but I am hoping for a bit of blast into the mainstream.
