I think your question can best be answered by saying that the XT series of radios will continue to do an excellent job of doing what they were designed to do, equipped to do and sold as being able to do. That hardly will make them "useless bricks". Expecting or hoping for anything beyond modest performance improvements at this point in time is most likely wishful thinking.
When and if evolving systems become prevalent enough to justify the cost of new product development, it will most likely come in the form of some "next generation" scanner.
