No, the only special features on there are 'monster files' about the silence and the Gangers. I think deleted scenes will be on the complete series 6 DVD box set later this year.
I got the bluray set earlier in the week from the UK. I watched the first two episodes of the wall screen, and the quality is outstanding. These really have cinematic production values. I planned to watch them all before episode 8, but I felt the need to watch Paradise Towers, as I'd kind of put that off... I should have stuck to Season 6.
