Does anyone know how long new versions of Python take to get into Homebrew? Will current Python 3.6 installations on Homebrew autoupdate to Python 3.7 when brew update/brew upgrade is run and the new version is packaged?
Did you mean pyenv? pipenv is a package manager. You can specify in pipenv which version of Python your project needs, but to utilize it requires that that the version is already installed on your system.

Almost correct. It requires either that the version is already on your system, or it can find an installation of pyenv configured in the standard way (and, on some quirky situations with OSX, configured but pristine--without any pre-existing Python builds). In the latter case, it'll ask you if you want it to automatically build and cache/install a Python of the specified version.
I don't see any pull requests yet.
3.5->3.6 python was updated in the same package, so I guess python 3.7 will replace python 3.6 too. You will get it after you run brew upgrade.
