Ray tracing will open up so many artistic opportunities that it'll be a huge shame if consoles are stuck without it for another full generation.
Edit: Actually, thinking about it more, I wouldn't touch next-gen consoles if they launch without ray tracing, because there's a good chance of a mid-gen upgrade console, like PS4 Pro and One X, that would support it.
