A future proof player is a ways off. Might even be a unicorn. Perhaps once we do have a universal player, they will pull the carrot away yet again. Multichannel will then be the next gimmick. This whole thing may be evolve into something like automobiles. They seem to never let me order the packages I want together(this engine with that transmission, or you cannot get this radio unless you buy leather seats, etc). Then, when it looks like it is one year away, that model gets replaced. Starting the whole process over again.
