Im an european, and here ps5pr0 is exactly 2x more expensive from discless base ps5 from launch.
45% stronger gpu, 10% oced same zen2 cpu, ofc 2x bigger ssd but still, price increase in 4 years alone is literally double, and now add another 4 years, which inflation wise very likely gonna be worse (u can see world economy is in the gutter, basically no middle class anymore and ppl living paycheck to paycheck even in 1st world countries).
And rememeber one more thing, ps5pr0 to ps6 will or at least should be much bigger jump than ps5 to pr0, bare minimum we expect is much stronger and newer cpu(zen 6?) more vram, and way bigger jump in gpu power than that tiny +45% pr0 got, it wont come cheaply
