I absolutely agree with you here. Sony made this mistake during their initial unveiling of the PS4 Pro and left many non-enthusiasts confused as to whether the Pro did anything outside of 4K.
Microsoft could really excel here by highlighting 1080p improvements. Especially if they have a decent game lineup planned for this year. Every game announced at their E3 press conference "needs" to show us performance on Scorpio vs Xbox One S first and foremost. IMO, 4K should be a footnote unless they somehow have a magical way to showcase it for the people who will watch via 1080p sets.
Yeah, i think MS will do a much better job for the layman, that difference is all that matters in real terms, which i feel they'll learn from Sony's botch job of a message. We had to get Gaffers scramble a thread together so they can assess what Pro games had to offer over PS4 games.
