A professional racing cockpit manufacturer based in Australia seems to have confirmed than Gran Turismo 7 will be be out this year this year which means it could be one of Sony's big launch titles for PlayStation 5.
Next Level Racing is an official PlayStation licensee, making very big and very expensive cockpits so players get a better simulation when playing driving games. On their Instagram page they asked "What racing game are you most looking forward to in 2020?" and posted four logos representing new games. Dirt 5 is shown and we know that's real, as is F1 2020 and AMS 2, the short name for Reiza Studios' Automobilista 2.
