16 studios here, some have multiple teams so that makes around 20-25 titles, some are for Vita and 30 is the total amount in development so we have nearly 10 more TBA games... who the hell are they coming from? I have to assume Yoshida meant 1st and 2nd party and there are quite a few more 2nd parties we don't know about, 2 of which maybe from Sumo Digital (LBP 3) and Level 5 (Ni No Kuni 2) as Mike_L suggested.

There was rumour of Uncharted PS4 being out sourced to Bend. I hope atleast their is some collaboration with Naughty Dog.

They can make a good Uncharted game, but they won't be able to match the Uncharted 2 standard let alone taking it to the next level.

While I hope Uncharted is great I want to see what ND can do with a new IP for next gen.  I would hate to see them tied down on a franchise if their hearts aren't in it anymore.  I want them to make a new fantasy world like Crash and Jak before.  That way they could escape the confines of a real world game and flex their creativity because while I love Uncharted and LoU (playing it right now and loving it) there aren't enough new worlds these days and I know ND is awesome at making them.

he said 20+ in its first year so possibly more?

Too bad Insomniac betrayed sony.. they could have made some great games for ps4. Instead... they failed with Fuse and now making a farmville-like exclusive for XB1. It's like seeing a good studio go down the drain.

How is sunset overdrive like farmville? lol. Why do you think they "betrayed" sony?

I just hope some of these are launch titles. There lineup right now is ok. I think theres only like three games. Knack,kz shadowfall, and driveclub.

well 20 are first year, so even if launch is lacking you won't have to wait long. Plenty of third-parties for launch or very close to launch too.

oh ya it really isn't that much of a problem. I'll prob pick up watchdogs/bf4 or kz at launch. I just wish iss was still a lauch title though. I think a gimped version of driveclub is free to with ps plus.
