Well, wait to see how support goes etc... In the meantime take on Keras or Lasagne, and do your stuff, i.e. acquire hands-on experience now. When time comes that you need to go into production, or you need a model that is not available in your current lib or framework, then consider a switch. Point being that experience acquired with one framework will empower you whatsover. In my view, these frameworks are like programming languages, you do need to pick a new one up from time to time, but you can do most of the things with all of them.
