Xbox Series X / Lockhart could be the last Xbox consoles ever made.

[Pyro as Bill]

XB has morphed into Microsoft's Kindle and is going to be around for at least a gen or 2.

I've yet to see a sub-model fail even though at first glance it could/would kill the established order.

By the end of the next gen, Sony will be offering a sub much closer to the value MS's sub has and Nintendo will be starting to add Gamecube remasters to the Nintendo-online sub.
