The reason is simple and obvious and definitely true !! 
It's because they are (finally!) planning to introducing a built-in TV Tuner on the iMac !!
They will need a full re-design of the remote to act as a TV Control which is why they haven't bothered improving the present one ..... mystery solved !!
In the meantime, which product out there is the best TV tuner for an iMac ..... Elgato or Miglia or somebody else ??
