Before people start crying that I included unannounced games, I only included studios with strong rumours that are making a new IP, if I listed any games I would have listed Bend, London and etc, but I didn't as those studios don't have any rumors of new IPs being developed unlike the ones I listed. As you can see above its obvious Sony are more focused on new IPs, with Microsoft new IPs they don't even own a few of them, I wouldn't he surprised to see TitanFall 2 on PS4. Also Sony have shown in the past late last fen they are focused with new IP with Puppeteer, Rain, Last of Us, Beyond and etc.
