I hear you, man. It is nice to have the tech match up, but years ago I decided to get out of that rat race. For a long time, I did it and spent so much $ needing to have the latest and greatest, especially with TVs and PCs. For me personally, whatever the latest thing is almost immediately becomes the new standard that I no longer appreciate. It's like the first time I got a 4K TV. I was blown away but it only lasted a day or two. Now I only notice it if I look at a 1080P TV. I got a new TV a year ago that was a lot better than the old one and it was the same thing.
I have no doubt that the new console looks great on your current setup. Sure it will look even better with 2.1 and 120hz but you'll be able to get that for less than half the price in a few months. All of the tech industry is a brilliantly marketed deal designed to drain our bank accounts (can't really blame them because profits are what it's all about). Several years ago, I paid about 250 bucks for a 4K TV on a Black Friday deal. My brother bought the same TV for over 2K when it first came out.
All that being said, if I had more money than I knew what to do with, I would buy everything new that came out!
Chasing tech used to be my thing. I've worked/work in a tech world and it's always interested me.
A lot of times I did swing and miss with technology.
When I was in high school I invested in a reel to reel system because that was supposed to be the best for audio.
I had the most high end car stereo I could afford. I was always upgrading.
I bought a Commodore VIC 20 pretty much the day it was released. I loved that little computer.
I purchased a Betamax because I **knew** that technology was the best
I was a huge Amiga fan because it could do things a PC couldn't do (multi-tasking was one)
I eventually turned to PC and every year or so I upgraded to the best PC I could afford.
I bought an expensive VCR because it could play any standard (NTSC/PAL/etc.)
When CDs came out I was one of the first to buy a CD player (at insane price).
I was one of the first people to buy a HDTV. It was a 65" rear projection TV I got from Sears. It was an insane amount of money; especially when you considered there was ONE channel that had any kind of HD content. It was PBS, and let's face it, not all their programming was interesting, but the visuals amazed me.
I got a PS3 because it offered a Blu-ray player. After I retired from the Air Force I worked on the road and for entertainment I watched movies a lot (2007). I paid Netflix extra for the Blu-ray option. Playing games was an afterthought because I had a very capable laptop to play PC games, but eventually I migrated to the PS3 to play games.
My last foray to tech was when I got a 3D TV around 2014. I hoped it would catch on because I love watching movies in 3D. I had Lasik surgery in 2002 and until then I had no real depth perception, even though I was pretty good in sports. Before I had Lasik I could not enjoy watching a 3D movie because I could not see the 3D. I signed up with ESPN 3D and watched all the events they showed in 3D. Even the World Cup I watched in 3D, and it was amazing to see. It added an element that was amazing.
By then I started to get burned out. The 4K TVs hit and the upgrades kept coming and I thought there was no sense in trying to keep up. I was happy with my TV and as I got older I knew there was no sense in trying to get "better" because I was happy with what I had.
However; with the PS5 I'm hypnotized by it and I REALLY want to take advantage of it's specs and I'm willing to spend too much money to get a TV to match it's maximum requirements.
