It depends on what you mean by support. If you mean will the development and revision to 2012 continue, I suspect that ended several months ago when they started working on 2014. If a fatal error is found I would suspect that even thought they are working on 2014, they would fix that. However after nearly two years of use, I doubt any fatal errors will be found.
If you mean will they continue to provide assistance with those using the program, it will probably continue for some time. I believe you can still get assistance for Version 16
I am sure it will not be like Microsoft is doing with Windows XP and basically removing it from the system.
