Answer is No.
It seems that if you want a new version of an application in SCCM 2012 you can use Application Supersedence
...So in theory I could detect the drop of a new production .msi in a folder and then automate the supersedence with powershell.
Now I am thinking this is NOT a good idea for production in my environment, really this question was me thinking by writing things out. I am attracted to the idea of continuous deployment, but not to production (in my environment).
