I think that unlike the dvd's this release will be one that goes OOP quite quickly unless its a storming success and paves the way for more Blurays.I might consider buying it when it's dropped below £15 by the end of next year
The optimistic members of Bluray.com are talking as if its a given and they even expect Colin Baker, McCoy and Hartnell Bluray releases. Yeah right!!
The team that put this together admit that the BBC told them to get lost in 2014 with regards to putting SD on Bluray and I suspect that beyond perhaps one more Baker and maybe some Pertwee this Bluray series won't last in the long term.
For US viewers there will be benefits of improved picture quality that the UK won't see as much so I think its selling for the bonus features and I can't see them being able to put together such an impressive package for every season.
