The response to PS3 is why we couldn't have PS4 Pro and XBO X like consoles on day one. The mass market put the brakes on expensive, high end console gaming.
Don't buy into the hysteria around Pro and X adding to development. It takes very little time, and very few people to optimize for these mid gen upgrades.
As someone with PSVR and a 75" Display, I can assure you my PS4 Pro and XBO X do not feel like cash grabs in the least. Even if the only difference is resolution, having the Pro at 1440p vs 1080p on the OG unit makes a huge difference. I even find it worth while to play games on the X over the Pro if it means the difference between 1440p and 4K. Resolution alone makes a major difference the larger the display gets.
I would feel truly cashgrab if Pro has separate exclusives, you spend $400 on PS4 in 2013, then another $400 on Pro in 2016, just to play many games, a rip-off:
-If only players realized that specs are important and could pay like $630 on the PS4, a game like Cyberpunk 2077 wouldnt be a problem if was equivalent to GTX 780(which was the best high end GPU you would get in 2013) and if GTX 780 was underpowered compared to the PS4 CPU
A example why CPU is important: from GTA SA to GTA IV
for RAM: the frame rates of Skyrim on PS3
for GPU: i dont know, its just graphics and resolution
-the Xbox 360 costed $526 in 2005, which is equivalent to $627 in 2013: https://www.gamespot.com/articles/microsoft-taking-126-hit-per-xbox-360/1100-6140383/
