Something I've been saying since the beginning, nice that people are catching up...
FTA: "The Xbox Series S was cheaper, but lacked the horsepower of the more expensive Series X."
It's not just that, the Series S lacks the power of the PREVIOUS GEN Xbox One X. The RAM limitations makes it impossible for it to run backwards compatible titles with the Xbox One X enhancements. AND it doesn't have the 4K Blu Ray drive present in both the Xbox One S and Xbox One X.
This is the first time a console developer has released a new machine less capable than equivalent machines in the prior generation.
