Those games don't have clout like GT does though lol. The GT7 trailer shown in June is the 2nd most viewed trailer of any next gen game. If GT was coming in the next year, Sony was gonna MAKE SURE GT was present at that event in some way, shape, or form. Even if it meant just throwing Kazunori Yamauchi in front of the camera for 60 seconds to talk about Michelin tires in Gran Turismo 7.
It was mostly to say that GT7 was absent doesn't mean that it will come out in 2022 or beyond.
I think like some people. There will be a special event. Once PS5 is released, communication will be more spread out, I think.
