Forget about the Pro and the X, its not like they gonna have exclusive or separate, they just play the games at 4K with slighty better graphics
Sony was trying to avoid the miskates like the ones with PS3, Microsoft well wanted to go greedy in the first place with the stupid always on kinect, always on DRM and $100 more
So you complain about being underpowered, but you cant think about the price if wasnt underpowered
Forgot to include that into my previous reply, but what guarantee do we have that there will be no games which won't run on the base consoles? After all, when the next gen comes out, supporting the mid-gen upgrades will be way easier than the base consoles. While it's not going to happen anytime soon, I could see that happen in around 2021-2022. Or they run as well as many later games did on a base 3DS, they were technically running, but with singe-digit FPS and thus almost unplayable.
