I think the all England-all the time is what is really killing historicals. Twenty years ago we had too many TSTL heroines and virtually no male POV, but we did have a multitude of settings: westerns, the Caribbean, more of Europe (not just England, Scotland, and France), even some Russia. Personally I would love to read more books set in China, Japan, etc. But I burned out on historicals a few years ago. I have a ton of newish ones in my TBR pile, but haven't been in the mood to read any.
It all goes in phases. Five or six years ago it was hard to find good contemporaries. Sooner or later there will be a big break out book again for historicals and they'll pick up again. And then we'll be lamenting the lack of paranormals or something
