App developers have already trouble "jumping" onto the latest version of the one or two mobile platforms they support, I doubt there would be much enthusiasm to add another one to the bunch. Indie developers often support only one platform because any more than that is practically infeasible with a small team (n<3) to do if you have a modicum of respect for your clients.
