My best guess is Resistance. Sony bought Insomniac. We are already getting a Ratchet sequel and a smaller Miles Morales game. Insomniac could use time to come up with more ideas for Spiderman 2 so that it's a proper sequel and not just a new story. In the meantime, Resistance was a great series and with Killlzone devs having moved on to Horizon, there are no AAA shooters exclusive to PS. I never played Killzone outside of Shadowfall, and don't know if it ever was as good as Resistance, but honestly it didn't look like it.
Twisted Metal would be cool, but Jak and Daxter seems unlikely. Neil from Naughty Dog said next game would be Last of Us 3 or something new, depending on the best idea. Jak and Daxter doesn't fall under new, but maybe Cerny is pushing to get someone else to revive the series like Sony is doing with Uncharted.
