I agree to an extent but they are usefully kept somewhat separate. The introduction to the great "Encyclopedia of Fantasy" put this well. Re: Fantasy :
"Its roots go much deeper into history, and its concerns are more archetypal" [1]
There can be a lot of cross-over of course. Right now, "fantasy" (perhaps of the "romantic" variety) seems to be a juggernaut and is taking over.

Checks out - for a while there, the future seemed appealing.. right now, I would guess most folks would prefer to escape into the past.
