You know, after seeing the way that Ken Follet's Pillars of the Earth was butchered on TV (with the first 4 episodes being faithful to the first 1/8th of the book, then the remaining six episodes trying and failing to do justice to the remaining book), I have exactly ZERO desire to see the Wheel of Time made into any sort of television series.
For one, Jordan got progressively longer-winded through the middle books and I don't think it's possible to make an interesting TV series covering all the book material without heavy cutting/editing for content. For two, a lot of the books wouldn't lend themselves to TV well given how much you're in the characters' heads. Three, I don't think even if you tried to go all Game of Thronesy and do 1 book = just under one TV season that you'd be able to get it down to a reasonable length.
Some works of fiction simply don't need to be on TV. WoT is among them. Now, some of Brandon Sanderson's work (the fellow who finished off the series after Jordan's death) actually might, but not within the WoT universe.
