We mentioned that Terry was in talks with Prime Focus in a latest DWM
Not a lot of news really. I spoke to Rod Brown at the Snuff launch last year and he told me some stuff that I um under an embargo so I can't mention.
What I can say is that Terry is involved in the series and that the series will be considered Discworld cannon. Should a character get killed off in the TV series they won't be in any more books and vice versa.
