There is no question, I use my system 90%+ for television and movies. I have never been an audio person, but I do have a distributed audio network in my home...
Well, if that counts, then 50% music. But, that is for background music while I work and get things done around the house. My main system, when it is on, is almost exclusively playing a tv show or a movie. I already have been struggling with the compoennt video issue as I have 5 component sources... and only 3 component inputs on my receiver. So I will likely end up with something just like the 3-Play.
The future? The future is all about HD discs for me. I have almost no interest in purchasing another movie on DVD when I know that I would much rather have it in HD. That's where I'll be in a year or so... waiting in line for my Blu-Ray PS3.
