I think Microsoft unveiled the Xbox Series S because of Nvidia not Playstation 5

 I think Nvidia pricing of the RTX 3000 (3070, 3080 3090) series graphics cards made Microsoft unveil the console, i dont buy that it was "leaked". $300 is not bad tho but they really don't have any games that is convincing in my opinion, I already have a Xbox One X and to me this might be a slight downgrade because it can't do 4k. But they do have a financing option, that is going to be the gut punch for Sony. The ball  is in their court.
