if u wait u will only see something better while ur waiting
a new range of hd tv's are out that have built in computers (for networking / playing of divx / pictures / mp3s ) still in its early stage but looks like a good all in one solution as currently getting all ur content to play on is a complicated business. I currently use an xbox1 to do it all (using xbmc)
i hope by the time i have to go over to digital someone has some sexy nice HD content and a nice way of getting it into my house and allowing me to use it to record the shows to a hard drive and play my networked content from any other source (external hard drive / NAS / pc / mp3 player etc)
