Game wise Sony dominated MS, not only showing double the exclusives but also talking about features that matter for games like: Backwards compatible solution, demo streaming, Viewing what friends are playing, Universal remote play and play whilst downloading.
PS4 showed 5 exclusives: Killzone (live demo), Knack (Ingame trailer ft gameplay), Drive Club (gameplay trailer), Indie game (gameplay trailer), Infamous (in-engine teaser)
Xbox One 2 exclusives: Forza (gameplay trailer), Quantom break (live action+CGI, potentially 3secs of ingame footage teased at the end)
The fact that sony showed twice as many games, all viewable back in february and microsoft can only pull of 2 makes think that the rumours of them struggling with 1st party software is true. Either that or E3 is going to be a nonstop tirade of exclusive AAA titles, equally its possible sony has already blown their load but I highly doubt it with media molecule, naughty dog (team 2), gureilla project 2, santimonica, team soho all having new titles being confirmed since 2011.
Oh and lets not forget The Last Guardian team.
