There is a console already, it's called Xbox Series X. The question is whether they need a second console.
MS is a very innovative company as of late, willing to try things. You'd be surprised how much the company has changed.
Change isn't surprising, I mean PMI don't sell cigarettes anymore and MS don't sell consoles (j/k) What market would they be aiming for if they put lockhart in a laptop instead of a console? The cheapest is always the big seller, that's why PS4 was such a success. It was just a stroke of luck it was the most powerful too. If they take lockhart out of the console space and put it in some no man's land between cheap gaming laptops and the iPad market they will just hand the console market to the Digital only PS5 - which will be the cheapest console then.
