BC was dropped because we switch architecture with this gen. A head of an company which doesn't support a feature says it's not relevant. News at 11. There are rumours that sony delayed the ps5 launch to get bc right, since they want to transition PS4 users faster than ever and lock them into their ecosystem. I think exclusives are overrated in terms of selling a console, because most games played will be FIFA, COD, fortnite and GTA anyway. You won't be able to play Halo, Forza or any other MS IP outside of Minecraft on an Playstation console. As for your other question. That's something Microsoft needs to worry about. Clearly some enthusiastic people bought an X/Pro despite them having 0 exklusives. Series X should be able to play games massively better. Microsoft already talked about the idea of 60-120FPS and more improtantly we have Turn 10 talking about real time ray tracing in their GCD presentation. Thus exklusives features between the ports could be happening, because i don't see any xbox one being able to handle real time ray tracing. Additionally the rumoured specs for Xbox and PS5 let many come to the conclusion, that these companies will eat a loss, if they sell the console for 500$. Thus someone interested in building an pc could be interested in rather buying a console, because of the cheaper price. And obviously it's only 1 year and after this period the console will get next gen exclusives.
