It's very, very unlikely that Dish will develop, or continue to develop, (2) software versions for Hoppers w/ SlingJsheridan, do you have any idea if this will be a "forced update" or will we have an option as to install it or not if we're happy the way things are now?
Remember, an update for the Carbon interface a couple of months ago added the "Classic" appearance. My money says when they push the interface to all receivers, they will default to the "Classic" interface so that the change isn't too drastic for some people.
