A small number of developers push back when they see new things in code, but most will eventually give in. The language has changed, and they need to either adapt or die (figuratively). I have not seen any serious resistance to adopting the features when they are available on all the target platforms.
Annoyingly at the last place I worked I did see this, with arguments (without seeing code I might add) that C++11 features are 'too easy to misuse' or 'ugly' or 'hard for new people to understand' (although my reaction to that last one was 'they need to keep up with the language then'). I was pushing for adoption (mostly in C++ tools, with some features as the compilers allowed, MS being the limiting factor) but it felt like hard going.
New company is actively picking up C++11 features as they make sense/are supported; the main barrier for non-platform specific code using C++11 features was Android, but with moving across to Clang the limit is pretty much, again, the MS compilers which dictate feature level.
The difference seems to be 'older, battle scared, comfortable' developers vs 'keen and punchy' developers (not young, by any means, but just more energy for things) and that itself might come down to the company in question and the mindset of those working there.
