Why is it desirable, only by a "small" number of PC gamers?.
Because most people, by that basically all console gamers and even most PC gamers themselves don't play on 120fps setting due to how taxing it is for the system.
Don't get me wrong, I am not saying 120fps is coming to consoles anytime soon, it really isn't in any meaningful way, the primary display consoles use are Televisions, which generally are 60hz panels anyway. (Or use some kind of frame interpolation to fake higher rates. It's nasty.)
Than so those 240Hz TVs were lying to me? Damnnnnn.
We both know that only if they have the "pro" version with more CPU they will have a more standard 60fps on consoles. Base console will mostly keep focusing 30fps and giving all else to graphic. So far Sony and MS have show that they prefer to have the graphic "twice as good" than twice the framerate.
