From what I've learned so far, I think 599$ is still too optimistic for Series X. For context the Xbox One X was 499$ in
2017, the Series S will have a paired back GPU(6TF->4TF, 12GB->10GB) and a vastly superior CPU, storage solution and feature set, so wouldn't it be reasonable to expect the Series S to at least arrive at the same price point as the One X? Now if the Series S arrives at 499$, how much of a premium do you think the Series X would have to command to justify its existence on the market? Maybe add another 200$-300$...
The funny thing about this situation is that console plebs will cry about having to pay the cost of these high-end consoles and pc plebs will cry about their 1000$~ 'mid-range is enough for everybody' builds being rendered obsolete. Everyone gets shafted equally.
Getting a bit tired of talking about the hardware, what about the games?
