High-end is something that is exclusive an expensive, so here is your problem something that it is relatively affordable is not high-end product.
From Oxford dictionary - denoting the most expensive of a range of products.
So yes it is high-end PlayStation, high-end console, but it is not high-end gaming device. When you think about high end cars you don't think about VW or Ford. you think Ferrari, RR, Lamborghini, Bugatti or some other luxurious less know car brands, when you talk high end watches you don't think about Omega or Rolex, but more about Patek etc.
If you are after high-end gaming, it is PC - powerful, with latest CPU, GPU and crazy amount of fastest memory etc. That's high-end gaming device.
Price wise for PS5Pro is too expensive compared to what it offers and what was shown so far, but if there customers wanting to buy it is fine by me. I just spent same amount of money on ROG Ally X last month while as I got too tired with steam deck issues (still got both), my PC is a bit older now, but still rocks cool 64gb DDR5, 4tb nve ssd and and gtx3090 and i9 12 CPU. Need upgrading but I am upgrading my PC every 2 gens (nvidia gens) now, so will wait till 5090 comes out and will probably go with 128gb ram and 8tb build. That's my friend played on big 120hz 4K Oled monitor is high end gaming.
