Yea I hear you. After Scorpio and Pro I just about got up to run out to buy a 4K TV with HDR.Money isn't tight, I just think that between PSVR and the Pro, I'm spending a liiiiiiiittle too much on gaming, which I wouldn't mind really if it actually made a lot of sense. But as it stands, without a 4K TV, it still doesn't make a huge amount of sense. We'll see, I have 9 days to be convinced.
But it's a ton of hype/instant purchasing glorification. Most 4K sets suck for gaming at the moment, low refresh rates, terrible input lag. List goes on. Not to mention expensive af. I spent a lot of time talking with my group, and in the end, it makes sense to wait on the TV. 3 years time, you can expect almost a 50% price difference in a large screen TV, but the consoles may at most move $100 dollars during that period.
Meaning, if you are looking at a $3K TV, you can save 1500 if you wait 3 years and get a better set in the process (for gaming). Save yourself even more if you wait on that 4K ready console until you own 4K. Maybe $100 + bundle, depending on when you buy it. Waiting certainly has it's financial advantages.
