The Keyword is "Sony's dev relation boss". Imagine if something like this was said from a Microsoft executive :P

He is just trying to charm up 3rd parties.

Sony is the only company that isnt making any partnerships for 3rd party exclusives. Though we have heard they helped Capcom with Deep Down, im unsure if its not just rumors.

He knows exclusives are important and there is clearly someone who gains from them. The consumer and therefore the developer/publisher.

He's right. Imagine how much more Super Mario 3D World will sell if it's on PS4.

That's more than one word, hence you should have used plural words.

But seriously, you have a Head of Developer and Publisher relations, saying something at International Festival of Idependent Games, and you think that he had 1st party games in mind?

Why not?

I think he's trying to emphasize the new sony mentality of "we love the developer". A bit overboard here...

said the company who only got the sucess of ps and ps2 thanks to many third party exclusives.

You're comparing first party games to third party games?

Sony going 3rd party confirmed.

If Sony had 17 of the 20 all-time best selling games, he wouldn´t have said such idioticy
