If AMD doesn't have RT hardware next-gen is going to be very disappointing.
For us tech people yes, or those who are intrested in it. For most 'normal' people probably wont care, they see 'PS5' so it must be better then PS4. PS5 certainly wont match PC but its graphics wont dissapoint to a level that it will flop or anything like that. AAA games will look stunning, even more so then now. On the other hand, since MS is betting more and more on AAA/AA studios, and their DXR solution, with again Halo on pc as lead, atleast that looks quite promising.
The games don't have to be exclusive. They have to be present. You spend $500 for a GPU with raytracing and have three games to use RT with. You don't care whether RT games are exclusive to your $500 GPU or not; you just want games to use its features! Same with consoles. Same with VR. If you bought an Oculus VR headset, you didn't care whether the games on it were on PSVR or not as well. PS4 had some 32 games in the first 6 months in NA and many more promised. It had 80 in the first year. RTX offers 11 in the first year, maybe. That's niche.
People that buy a 2060 or any RTX gpu now dont buy it only for RT, they are capable enough. If i would be in the market for a new pc, i wouldnt buy a gpu without RT. A 2060's performance isnt too shabby, and its RT features are sure nice to have, Metro is mighty impressive. Yes not many games, but when one bought a PS4 there werent many games either, mostly multiplats, that certainly dont use all of its features.
It's not perspective at all. Raytracing hardware is niche! It's a tiny little portion of the gaming market and will remain as such probably until its replaced. A tiny portion of the market will have RTX enabled cards and a tiny portion of games will have RTX features.
Just like the One X and Pro's market is tiny compared to the base consoles? How much aside from resolution goes used? With the 2060 out the door, and seeing how popular the 1060 was/is, i dont think its that bad as some like to portray.
But we will see with RTX, maybe its a flop, maybe not. I do think that MS has some say in it too, with their DXR. It could be that hardware RT(X) is a thing for now and a couple of years to come, when we see new generation of GPUs landing with more flexible solutions. Like i said RTX 2000 is for early adoptors, people that want raytracing now can get it, and i dont think the list of games is that bad, i wouldnt expect a huge library from start, in special in the pc world. Hardware T&L, pixel and vertex shaders took awhile for adoption aswell.
