I don't even care that my TV has a tuner in it - two tuners in fact. It also has a USB port that allows you to view images and perhaps play tunes. None of it gets any use because I can already do that on other devices. My TV is now enclosed so that I can't even access any of its ports or buttons.
There's a big market for integrated solutions, but I don't think we're in any danger of separates going away.
My amplifier is just a power amplifier (though multi-channel). My pre-amp is however a pre-amp and DAC/processor.
This post comes at a very appropriate time, since CES just started. I'm amazed at how much has already been announced that will also soon be forgotten. Some of what's been announced will be irrelevant by the end of the week. Most of it will be all but completely forgotten by the end of the year. There are very few exceptions and so far nothing has really jumped out at me.
