However Visual Studio 2012 cannot run on XP, nor by default can produce binaries which execute on XP, so testing and developing for XP compatibility is going to become increasingly difficult.
As far as I know this is false. 2013 and 2015 have _xp toolsets that allow building for XP..
You may have missed my qualifier "nor by default". Also, the compatibility toolsets you mention target a much older STL and C++ support level. VS2015 claims it should be a 99% C++ 11 compliant implementation, so it will be the first MSVC where all C++ 11 codebases should reasonably expect to "just work", constexpr and all. That certainly can never target XP. VS2015 RTM actually also has a surprising amount of C++ 1z already in there. It's competitive with latest clang (sans relaxed constexpr and variable templates). I am quite amazed at the sudden leap forward by Microsoft actually, it shows just what they are capable of now they have started competing once again.
