Based on budget, is it too early to jump on the 4K bandwagon? I looked at 4K disc players and they seem prohibitively expensive at the moment, relatively much more than their display counterparts. Until my Yammy dies (I suspect I'll kick the bucket before it does) I can't justify purchasing a new AVR to support 4K pass through. I'm just looking ahead to see how I'm going to evolve my systems. Would it be better to wait a few years before jumping in?
