Luckily my setup is all in one place down in the basement. No extra cables to run. It'll be a simple matter of unplugging the old console and plugging in the new. I bought a new receiver in May as a graduation present to myself so sound and 4K switching are already in place. Now it's really just a matter of TV, 4K disc player, and gaming device. Since the X has a built-in 4K player, that checks two thirds of the boxes and the last is relatively inexpensive given the preferred 60" size.
I've always run a little behind the times on having an up-to-date setup, mostly for financial reasons. SWMBO and I are to the point now where we can be a little more proactive on entertainment things. TV and movies are something we both enjoy and equipment expense is modest compared to other things like cars, RVs, etc. It's also something with a perpetual return versus one-shot entertainment thing like travel so we're giving ourselves leeway for spending a bit on it. It helps that the setup is relatively modest compared to a lot of home theater setups, though careful component selection has resulted in a brutally effective system.
