I'm not confident in Bakker's (or his agent's) contract negotiating skills, based on how botched his Overlook books have been through the years, and how terrible the rollout of TGO has been in Canada (still not in the shelves as of this posting, even though its been out for 3 months). So, I fully agree with those concerns.
Scifi Syfy channel is doing Hyperion, and I fully expect that to be mediocre at best. Maybe he's selling the rights to Scifi Syfy as well, that way they can ruin both my favorite series all at once and I can put these dreams of grandeur to bed.
Hopefully though, HBO or Starz or whatever premium channel picks it up and they give it a fair shake. It'll need some creative scripting to get through all the internal dialogue, all the different POVs in the first book, the background info stuff, fixing the pacing to work better for a TV fandom... It'll take a lot of work - lets hope whoever is buying the rights is interested in doing that work well.
