At the beginning of Sony’s Gamescom 2013 presscon, Sony Worldwide Studios head-honcho Shuhei Yoshida presented the PS4’s interface in a very relaxed way. He browsed the menus, checked a couple of games, went into and watched an ongoing Killzone: Shadowfall game stream, then proceeded to join the game. He then uploaded a screenshot and capped it all with a tweet to start the show.
Very classy, Sony. I really like how the interface shows all info about the game (like trophy count and friends, etc) just by hovering on it.
Can’t wait for launch.
