Williams is a far better example, but he's an exception, in that he specifically chose to rework and modernize a known type of story (LotR). In general, such authors have their own ideas, and don't have a whole lot of use for the setting and character conceits typical of D&D.
Basically, if you're really good at making up your own world and getting paid for it, why do you want to borrow someone else's?
I disagree that Williams is an exception, I find quality, mediocrity, and crapitude in all genres I'm familiar with, including BFE (Big F'ing Epics).
First, a few things about Williams (not to prove/disprove a point, but just because I love him so): The "Memory, Sorrow, and Thorn" trilogy was written "on a bet" so to speak, but that doesn't change how amazing it is (not that I think you'd disagree). Also, it isn't the only BFE in Williams body of work. Also check out his "Otherland" series (4 chunky novels plus a novella), "Shadowmarch" (4 chunky novels), and "The War of the Flowers" (only one novel, but very chunky). All excellent works of fiction (IMO).
But all that is beside the point, we can all trot out good and bad examples of the form and criticize the weak points of even very popular series ("Wheel of Time"). All I really started with is "this is what I'd love to see", which you can't really argue. What we're really debating is "it probably wouldn't be a good idea for WotC to pursue this type of work for various reasons".
I think that writing a BFE would be a lot harder a task than a more standard 300 page length story, and the difficulty would be compounded with each extra book in the series. My dream, of seeing a ten-chunky-book-plus D&D epic would be a serious task for any author. More difficult for the author(s), more difficult for the editors, more difficult for WotC . . . especially if they tried to tie it into their various game lines like the recent "Neverwinter" series. But I think it can be done, and be done with quality. And personally, I'd squee like a little girl if WotC decided to tackle this type of project and pulled it off.
But, getting back to my original post . . . it's what I'd love to see WotC do. For my own selfish reasons. Can't argue that!
