I think what you are missing, is that unless Sony is willing to compromise on the quality of thier games, I doubt they are going to push thier tentpole titles out the door early, especially with how things went this gen. Sony 1st party was incredibly successful, and garnered rave reviews for games because this didn't cut corners, they finished games, and polished them up to Nintendo standards, but with industry leading visuals.
Like, I think they will have to push some titles out the door, just like they did with PS4 to get themselves rolling, and they might have an ace or two up thier sleeve, but I expect them to copy thier strategy from last-gen, and cook a large amount of content for 5-7 years each.
With regards to game timelines:
- Uncharted 4 released 2006, Last of Us 2 will release 2020. Do we expect them to spend less time on thier next game, with new tech and significantly greater art requirements?
- Killzone 3 launched 2011, Horizon launched 2017. I've also heard 6-7 years from knowledgable people before. Once again, this is a huge open-world RPG, they will be upgrading their technology, do we expect them to really second less than 4-5 years? Maybe, but I doubt it.
- Insomniac, I'm not entirely sure. Sunset Overdrive 2014, Ratchet and Clank 2016, Spiderman 2018. I think they definitely could have the ratchet team working on something. On the other hand, perhaps the ratchet team got folded into Spiderman? I expect Spiderman 2 to be thier highest priority, and I could see that taking at least 4-5 years given Sony standards.
Oddly, while Polyphony digital is know for taking ages for sequels, I could see them taking GT sport, and perhaps finally use outsourcing to pump out a fleshed out GT7 quicker.
I can also see Sony Japan studios having at least one or two games in the works for launch or close to it.
