With Python 3.3 the venv module is now part of the standard library and the interpreter itself has been modified to support the isolation that the virtualenv had to use hacks to make happen. In Python 3.4 the venv module installs pip by default as well. As one of the maintainers of virtualenv, it's my goal to move that project so that it will use the venv isolation mechanism when it is available, and have virtualenv just provide a level of UX overtop of it as well as shims for versions of Python that don't have the venv module.
