Man if PS5 Pro is 21TF then Microsoft absolutely NEEDS to counter with a mid-gen refresh of their own.
I dont think they could take the increased beatings and last the rest of this generation without major brand damage.
Something like 15TF fine yes PS5 Pro is gonna win out 100% of performance comparisons for the rest of the gen but it wouldnt be enough of a difference in performance to make everyone jump to the other side of the fence. But 21TF would be HUGE.
We got a whole thread about this what if. At the end of the day the games are what matters. If a GTA 6 is best played on the PS5 Pro, it will hurt Xbox in my opinion. If Fifa, COD, and others games work marketing deals with Sony like Hogwarts legacy did it will really hurt Xbox too. As for what Xbox can do... Hard situation for them no matter what IMHO.
They'd be better off moving to next gen early than throwing more good money after bad trying to compete in the current generation. The boat anchor that is the Series S is going to fuck them for the rest of the gen.
The problem with that choice is that they can't decide when a generation ends and when a new one begins. And they would need to find a way to make Gamepass users that are still mostly on the Series S and X happy. And being too soon would mean allowing Sony and Nintendo time to do whatever they want. There is not that many options for them IMHO:
Continue the generation and have a Pro like Sony, or a better one one year later like they did with the One X. They have said publicly that they are not planning that for the moment. And it will not save them as having 3 consoles will make their marketing harder.
Do nothing. Have a Slim version and wait for next gen. Even worse in my opinion.
Go next gen early. But it would mean doing nothing at first AND risk being the Dreamcast of next gen. Can work, but with tech being slower to evolve I can't see them investing enough to stay competitive with a PS6 that have 2 or more years to launch.
