Aaaaaaaahhhh, what does soon mean? What about all the Verendus rumours?
Shuhei isn't going to tell us what kind of games they're making. He won't even say what kind of games Bend and Sucker Punch are making. He only acknowledges they exist because he knows we know they have something coming.
Outside of Team Ico and Team Siren (Gravity) we don't know what Japan Studio is developing internally. That studio is huge. It was 400 people last I heard and that was years ago. I'm willing to bet that their collaborative projects, small VR projects, The Last Guardian, and Gravity Rush 2 might have 200 to 250 people tied up right now. So what are the other 150 to 200 people working on? Because we know it ain't Vita.
