It doesn't seem like there's an overall shortage of 3rd-party games in the 8th Gen, at least as far PS4, Xbox One, and Windows go. The Wii U had a very clear shortage of 3rd-party games, even for a Nintendo platform. If you consider Switch 8th Gen, it's had a lot of 3rd-party support. A lot of indie games, ports, and shovelware. But it's still a lot of support.
There does seem to be a lack of 3rd-party exclusives, which were very common in previous generations. Also, there is a very heavy reliance on ports, remasters, and remakes. For someone like me who missed out on a lot of 7th-gen games, I don't particularly mind it. But I understand the frustration.
