I also am not exicted about or interested in the frame generation, but Frame generation and Ray reconstruction are presented as being independent from each other 
But i also don´t have to worry about that, because I cannot use Frame generation, since i only have a RTX 2070, so if anything, i could only get ray reconstruction, and thats the one i am excited about.
And since they used Cyberpunk as one of their testing grounds, i tried to find that place, they showed in the video, so that once Phantom Liberty and DLSS 3.5 gets released, i want make a comparsion to what it looks for my system.
So it will be interesting to see, if Ray Reconstruction really will be a separate option to turn on and off, just like its right now with Frame Generation and f.e. DLSS Super Resolution.
And i found it, its in Heywood - Vista del Rey, close to the Metro Congress and MLK fast travel point, if someone else want test it ^.^
How it currently looks for me ingame:
