There was a thread about sony's first party titles. They have so many titles coming that we cant even know what is coming earlier/later. GT Sport has a Beta starting tomorrow, the game was supposed to launch last Fall so they for sure can have it ready before summer, but at the same time there is no need to rush.
There are titles like Crash (not 1sst, but it's a 'playstation franchise'), Wipeout are also coming to fill the 'lack' (what lack?) of games before fall. On Fall there will Destiny 2, the usual Call of Duty, Assassins Creed...
I guess Sony can just wait and release their titles when it's needed, they are probably waiting to get more info about Scorpio launch titles and stuff. I can see Sony holding GT Sport to release 2 weeks before Scorpio just to have a big hit (we cant forget Mario is coming around the same time!). Before that we could get Uncharted (august/september), and for next year God of War in March as usual starting the year hot (as Horizon now).
There is a Spiderman movie coming in July, so I wouldnt be surprised if the Spiderman game would come right after it too. They can have a great presentation in June on E3, then the moie comes and then the game.
