In my opinion, I think that sticking it to the Playstation 4 would be a good idea. It would raise up more consumers to purchase the PlayStation 4. Next thing you know, most of the franchises be continued on the PS3. However, I believe that the PS3 is a good idea too, since I am a PlayStation 3 player, myself. But just for Sony to get more money, releasing this awesome franchise on the PlayStation 4 would be a good idea.During an event in London, Sony announced that they have this game in mind for the future, to be played on the PlayStation 4 console - which is Sony's latest console in development.
Kazunori Yamauchi, the Polyphony President, also added that for the holiday season, it would be best to release it for the PS3 version. He wants the game to come out, with DLCs releasing in a few months after its released. Sony did announce today that a demo for the latest franchise to be released from the creators of Gran Turismo will be released in July.
