Elgee, if GoT or Daredevil is a good gauge, I'd say that once some of the pieces have been identified, such as writer and director, we could get it within 3 years...maybe earlier if casting goes quickly.

Serious77, funny thing is, the "premium" channels episodes are a full 60 minutes due to containing no commercial slots, whereas the "network" episodes usually are around 40-42 minutes because of all the commercial breaks.  The resulting difference per season is only a couple of hours of actual time.

I honestly hope it gets the "Netflix-Hulu-Amazon" treatment.  I'm a huge fan of GoT, but WoT doesn't fit with the typical HBO-Showtime nudity/sex/language format.  And the only thing I've seen on Cable/Public television that could do WoT well and accurate,  I feel, is on AMC or SyFy.  I think putting on SyFy would be a death sentence.
