Funnily enough its my birthday too, but two things to point out : PS4 Pro does not support 4K blu ray and if you want to buy a Pro you need a 4K tv to take advantage of it.
Regarding 4k Blu-ray, that's exactly what I said!
"and unless you really value 4k Blu-ray, then PS4 Pro will probably be the best pure home gaming system"t
As for the second part, that's strictly not true. Games running at 1080p on PS4 Pro can benefit from increased texture resolution, more effects, better reflections, improved draw distance and higher framerates. You don't need a 4k TV to benefit from it.
