There's no need for implications of deals between nvidia and game developers in smoke filled rooms. It's pretty straightforward: raytracing means less work for developers, because they don't have to manually place lights to make things look "right". Plus, they can harp about how it looks "realistic". It's not any different than the explosion of electron apps (and similar technologies making apps using html/js), which might be fast to develop, but are bloated and feel non-native. But it's not like there's an electron corp, giving out "electronbux" to push app developers to use electron.
