Not really. I have been monitoring what is going on with C++ for the past several years. Some of what is introduced by Boost has been rolled into the C++ language starting with C++ 11 but if you look at the roadmap since then and for the future the direction C++ is taking is not really to add Boost libraries but add things like module, better concurrency programming, concepts, and things that just make the language less prone to memory leak issues, that make it more usable for modern programming tasks, etc. Boost, and a ton of other libraries, will need to continue to exist but they should be written leveraging the new C++ standards so that they have modern interfaces.
isocpp.org is a good place to look at what is going on and you can find videos on YouTube from CppCon.
Microsoft plays an active role on the standards committee. Herb Sutter is always there. But, they aren't trying to push any Microsoft related technologies or anything like that. Besides, the standards committee is so huge it would never allow that.
If you check out the latest Microsoft compatibility matrix Visual C++ is a lot more up to date with the standard than it has ever been. Programming in modern C++ is a lot of fun.
