It is very likely that the RX 7000 series will in fact have ray tracing. Since RDNA 2 introduced ray tracing to AMD's lineup, RDNA 3 will likely continue to support it and likely improve upon it. With implementation and support in applications growing it is a staple in graphics. Therefore it would be terrible to take it out. However, the current AMD solution is less than ideal. And Nvidia easily steamrolls performance in ray tracing. So it's more than likely the next update will further improve on the tech.
