Please be excited for modules, coming out three years from now (plus implementation time).
It is actually a good thing that they delay modules. It is difficult to get right, but it is on a separate track so it can come before C++Next.
The most important parts of C++17 is related to ironing out language quirks and providing library additions: some significant improvements to meta-programming, file system support and C11 support which brings in things like aligned_alloc.
There is a significant signal in reserving the namespace "std"+digits, meaning there will be a major standard library update in C++Next (related to "ranges").
