Well i watched the entire E3 this year and in the Sony press conference they more or less said that they are in the "middle" of the cycle of the console and i think with all the next exclusives that are coming for the PS3 mostly in 2013 they want to give it more "life and importance" since, i don´t know about you guys but i play on PC too and the quality of the games on the PS3 lately is not as good as it used to (obvious) and literally i stopped buying games for my PS3 and only buying exclusives. Even i received a voucher code to buy a game for 1,49 in the PS Store a couple of days ago. (Hydrophobia Prophecy lol) And what about the new deals for PS + members...tons of free games.
I think they know what the problem is and they want to release fresh games and sequels (Beyond, GoW Ascension, The Last of Us, MGR Revengeance, Little big Planet Karts, PS Battle Royale, etc) as fast as they can before the PS4 will be announced...and i believe that could be happening, if not at the end of 2013 (at TGS), possible at E3 2014.(at last)
Think about it, they are going to release tons of games in 2013 and if they do, it is not logical to announce a new console right before that. They need time, developers needs time also for the next-gen games in the upcoming consoles to have a "successful" release with tons of games. (Vita sales are not so good because the lack of games)
It will be possible to see GT6 on the PS3. Don´t like the idea because is not going to be "way better" if they don´t get rid of all "standard" content (not the cars i mean tracks too) and the car list itself. The graphics details is what concerns me too because the PS3 is not capable to do more as it is doing right now. BUT if all cars are Premium, all tracks looking as good as the new ones (SPA, RACE X and Nürburgring because it is new not remade) and then having the features that we want,with a great car list, the game will be as better as we wanted to be after all.
At first i was not too sure about it until i saw this year´s E3. But that was the message from Sony at least for me. Possible will be but not because of that news...
"You told us earlier how interested you would be in buying the PS Vita version of the latest Gran Turismo game. Knowing that you might be able to get a discount on the PS3 version of the game, how interested are you now in the PS Vita version"
To me this is translated as they are going to release a Vita version of Gran Turismo but the "a discount on the PS3 version of the game" sure refers to GT5. (maybe not but the Vita version sounds like a 2013 release that it is in the works)
