Whenever I upgrade I move the old stuff from the theater to the livingroom. It's like getting 2 upgrades! Future proofing is not really possible if you want to always have the latest thing. With that said I just upgraded a receiver for the first time since 2009. Sure I didnt have atmos, or 3d, or 4k, but I was fine with it and didnt feel like I was missing out much. As long as you don't need to be the first guy on the block to try everything that comes out, this stuff can last you many years.
