First its not a port.... I think they made that VERY clear in the conference.
Secondly, every major studio today was a not so major studio at some point. And sony has a lot of studios. we are less than a year in and you expect every single sony studio to have announced their next game? I think it shows the amount of depth the company has when we are getting so many games from them and they still have studios yet to even show up. Don't forget, in its first 18 months on the market we are getting/got KZ, Knack, MLB, infamous, Driveclub, The order, LBP, Bloodborne...etc. And thats not including remasters or indie first part games.
Lastly, be patient.... should just give you something to look forward to for E3 next year. Something people seem to not notice, sony has so far revealed at least one new IP at every major conference this year. That means they are probably gonna show something at TGS too.
