According to Hermen maybe some MP GaaS potentially may end being released day one on PC. He didn't say that all of them will be day one, he said that we may see it in the GaaS area.
But also said, like Jimbo, that their priority is PS and make the games for it. He, like Jimbo in the past said that their idea was to focus their devs PS, and later have other teams who may port some of these games (not all) time later to PC.
They were going to test different time frames between the original PS release and the PC release for the ported games, being the most common distance multiple years. For the non GaaS title, he Hermen said that they were going to test the closest around a year of distance. But when looking at it, in cases of the Uncharted collection or TLOU its a distance from their remasters/remakes. The distance between the original PS release and PC release in case of TLOU is 10 years and in Uncharted 4 six years and a half.
The other ports of non-GaaS are released on PC around 2 or more years after release, and PS Studios still didn't release in PC any of their GaaS games. The ones that we know will be day one in PC (and in Xbox) are the Bungie ones since unlike PS Studios they will continue supporting all platforms with their games.
