Who reads epic fantasy?

This post was not only prompted by a remarkably stupid NY Times review of the "Game of Thrones" TV series, in which the reviewer thought the story was a polemic against global warming, claimed that women don't like fantasy, and further claimed that women do love sex, so the sex was gratuitously crammed in to please them.

It was also prompted by curious fact that while many of the most successful, and by successful I mean bestselling, writers of YA fantasy and sf are women writing under clearly female names, and most of the bestselling writers of urban fantasy are women writing under female names, most of the bestselling writers of epic/high fantasy are men or women writing under male or ambiguous names.

To quickly define terms, by "urban fantasy" I mean "Set in contemporary world much like ours, but in which magic and/or magical creatures exist. Typically involves romance, fighting evil, and/or detecting." By "epic fantasy," I mean "Set in non-contemporary world which is not just our world plus magic or an alternate history of our world, big sprawling stories, typically a series of fat volumes, typically involves a huge cast of characters, war, battles, monarchies, and politics. Typically set in a vaguely medieval period."

I have some questions for you all.

1. Am I correct that the bestselling writers of epic fantasy are typically male or writing under possibly-male names? I'm thinking of Robin Hobb (woman writing under possibly-male name), Patrick Rothfuss, George R. R. Martin, Robert Jordan, Brian Sanderson, Tad Williams, Terry Goodkind, Terry Brooks, etc.

I am under the impression that the female authors writing under clearly female names, like Kate Elliott, Katherine Kerr, are midlist or at least not hugely bestselling authors.

Anomalies: Jacqueline Carey - bestselling, I think, but clearly female. Gender of names may not be clear to readers: Sherwood Smith, Mercedes Lackey. I think Sherwood is considered a midlist writer, while Lackey is maybe in between midlist and bestseller?

2. Is epic fantasy really read more by men than by women? In general, women read far more than men do. Is epic fantasy an exception? I would love to see some actual figures here, because I honestly have no idea.

3. Do male or male-seeming epic fantasy authors get a bigger marketing push from the publishers? Are readers more willing to buy their books? Why is this different from urban fantasy and YA fantasy? (Maybe the latter are considered "less serious," because of the association with romance and teenagers, and so the proper province of women?)

(I don't even ask, "Is epic fantasy by women reviewed less?" because we already know that answer. All fiction by women is reviewed less than fiction by men. One of many statistical breakdowns to that effect here.)

ETA: A brief reading list of non-bestselling female writers of epic fantasy:

Sherwood Smith: Overview: Yo, epic fantasy authors. I'm real happy for you, and I'mma let you finish (uh, sorry, George R. R. Martin, I swear that was not a dig) but Sherwood Smith has already written one of the best epic fantasies of all time. OF ALL TIME.
