the one X is an updated version of that pretty much. and it is a shit ton more powerful than the Original X Bone and though the one S is more powerful than the original system and i hear a vast improvement the one X is an upgrade from that console as well. same generation too and it can play 360 games so far i think they have something like 400 i think?i may have the number wrong on that and it will later this year my guess around X-mas maybe? the one X will also play the original consoles games as well. on wikipedia it said the 360 could play only 480 games on that console on this one i dunno yet i hear it's suppose to be less but i find that really stupid cause there is no doubt a lot of great games on the OG console that i would love to play.
i'm really awful at saying what is on the One X and how powerful it is but it's on this site so check it out. so yes the One X will play the exact same games as the X Bone and the one S the games will just look far better on the One X than it will on either console.
