I was just watching the last video in the "Evolution of Playstation" series and the only game they went into full detail on was PS4. They went into its initial concept before talking about the commercial success of the series and how it reaches a new market. I think this a good indicator that GT6 or GT6: Prologue will be ready for the PS4 reveal.
They briefly went over their artsy games, so possibly a hint at Last Guardian since ICO and SotC were mentioned and shown multiple times. This may seem like overspeculation but if you're making a video on the games of Playstation a day before the reveal of your new console you would want to educate or remind people of these experiences if you're going to show new games in the same vein. If not why didn't they mention their other huge franchises like God of War, Uncharted, Spyro, Crash, Ratchet, Jak, Sly, etc. I don't think they even showed a clip from those games (maybe a brief flash but never mentioned by narrator.
It could very well be an indicator of GT6 and/or Last Guardian at tomorrow's showing...unless I'm just reading waaaaay too far into this.
