Facebook is migrating everything. The Instagram migration in particular got quite a bit of press coverage due to the PyCon keynote.

Other organizations may choose to not rewrite or migrate. At their own peril. Likely a third party like RedHat will continue patching 2.7 for their customers but no Python.org releases will be done anymore.

More importantly, after 2.7 EOL library maintainers will drop support like it's hot. And that no single player will be able to continue supporting.

So, you might get a few more years out of 2.7 but it will be an increasingly frustrating and insecure experience.
