I realise that this is a pre-order item but in my opinion it represents really good value. Although it includes the first of the newer Muppet movies (The Muppets) it also includes Muppets Most Wanted and the previously unreleased in the UK The Muppets Movie (1979), The Great Muppet Caper,The Muppet Christmas Carol, and Muppet Treasure Island.
I actually purchased the USA versions of the latter 4 and paid nearly as much for just 2-3 of them as this whole boxset is being sold for.
The only downside is that it's only partially complete as it's missing Muppets From Space and The Muppets Take Manhattan which were only recently released in the UK.
Plus it should come with a decent amount of Disney Movie Reward points for those who are interested in them.
Details from Amazon:
This product contains:
Muppets Most Wanted
The Muppets (2011)
The Muppets Movie (1979) [New to Blu-ray]
The Great Muppet Caper [New to Blu-ray]
The Muppet Christmas Carol [New to Blu-ray]
Muppet Treasure Island [New to Blu-ray]
This title will be released on August 4, 2014.
The description on Amazon states that it will be a 5-disc set so I can only assume that it will be like the USA version with The Great Muppet Caper and Muppet Treasure Island on the same disc and the rest being individual discs.
