If Sony PlayStation does an event of a format like last year with trailers about upcoming games, it‘s possible. Why they have to show anything? Because of Microsoft Xbox certainly will show a bunch of games, too. As member of E3.
Gran Turismo is a Perfect Game to show the perfection of new console and when they do it good, they can destroy Xbox.
I hope this year they will show really reasons for new console generation. GT7 trailer last year was a bit improved GT Sport for me.
