Okay, so I have a little (VERY little) bit of information to add.  This is unofficial, and maybe it is already known by many, as it's been a while since I've followed "what is known and not known" about the Wheel of Time TV series.

What I can confirm comes from a personal connection that I cannot divulge, which I know makes this post reek of tinfoil-hat smell.  I have a VERY tenuous and indirect connection to... someone at Sony Pictures Television Studios (more of a "I know someone who knows someone"), and that person is bringing this monster of a show to television.  Acknowledging that, you can choose to believe me or not.  This probably isn't even really news.

The series is being developed by Sony Pictures TV (we knew that, right?).  There's no cast yet, and to be honest I do not even know how far along they are, but I know they're still early enough in development that no one at Sony is even discussing casting yet, but the feeling is that the show will star mostly unknowns with one or two somewhat recognizable names, but probably not huge stars, unless the show ends up being wildly successful.  But it is absolutely going forward, enough so that some folks at Sony (and people connected to them) are all reading the Wheel of Time, many of them for the first time.  There is at least one extremely high-level executive at Sony who is directly involved in the show's development.  I can't name the person without breaking a confidence, but I do know who the person is and what their position within Sony is, and when I found out who it was, and I saw their track record on other TV shows, I was happily surprised.

I can say with some degree of certainty that the folks in charge of the TV show are taking it VERY seriously.  They are all keenly aware of what the series means to its fans.  They might not be able to accomplish everything that fans want to see (some corners are going to have to be cut, considering the medium of television), but they're really trying.  They're moving carefully, and thoughtfully, and the last thing they want is to release the show and have it reviled and denounced by the WoT fan community.  They do feel the pressure to make it something people want to see.  I couldn't begin to guess about when it might be ready for broadcast, but barring some kind of catastrophe, it seems inevitable to my untrained eye that this will be on your TV eventually, and not necessarily as a low-budget affair.  They are also aware of the Red Eagle "Dragonmount" pilot debacle.  They are keeping that in mind as a cautionary tale, to remind them that they can't just release a crap show, slap a WoT sticker on it and call it good.  They do want this to be something special.  They have ambitions for multiple seasons, but at present all their efforts are being directed towards making season 1 something they they can be proud of.

I hope this helps.  And I apologize if it does not.
