There is a not well documented command build into OSGeo4W Shell which sets the shell up to python3 as Luke mentions

py3_env

Basically it sethsets your PYTHONHOME and the correct PATH. Then you can call Python3 with python3.

C:\>py3_env
C:\>SET PYTHONPATH=
C:\>SET PYTHONHOME=C:\OSGEO4~1\apps\Python36
C:\>PATH C:\OSGEO4~1\apps\Python36;C:\OSGEO4~1\apps\Python36\Scripts;C:\OSGEO4~1\apps\Python27\Scripts;C:\OSGEO4~1\bin;C:\Windows\system32;C:\Windows;C:\Windows\WBem

Update with auslander's comment:

To use Python3 with the OSGeo4W shell that comes with QGIS 2 you have to change the file {path you installed qgis}\etc\ini\python-core.bat:

SET PYTHONHOME=%OSGEO4W_ROOT%\apps\Python36
PATH %OSGEO4W_ROOT%\apps\Python36\Scripts;%PATH%
