it depends what definition of 'exclusive' they used.
if they used the fake joke of a definition (in other words, its ok if its on PC, just not the enemy console), then maybe it includes games like warframe, blacklight retribution and war thunder, possibly even DCUO.

GT7 might have a chance of releasing next year on PS4.

whats happening then?

they said World Wide studios will publish 20 games. so anything that is published by sony counts, others do not. Resogun is published by sony, so it counts. Deep Down is published by Capcom, so it doesnt count. 

Oh I've got nothing against Japanese titles, I would actually prefer that over more Western titles. Next/Current? Gen needs some Exclusive JRPG/RPGs. Deep Down interests me....but depending on how Crapcom decides to do the online it might completely turn me off. I was liking it more so when I thought it was a Demon's Souls clone. 

There is a title I forgot, Exclusive Souls IP that is supposedly in development. Would be nice to get that. Lily Bergenome has my attention too. Sony's 1st party Japanese studios is very lacking these days tho. Polyphony takes WAY too long to release, and Japan Studios just is at a loss of direction. They need a consistant IP that they can always do to make them money. ND has Uncharted, SSM has God of War, MM has LBP, Poly has GT, Japan Studios has....? I would personally love....for Ape Escape to make a real comeback. Not the horrible spin offs that the last few titles has been. The first game was amazing. I'm ok with another Sirens, Tokyo Jungle, etc as well. They just need to be consistant with it.

Time has Passed....?

but only 2 weeks after release

Oh right I forgot about demon's souls 2

Delays, cancellations and creative lying most likely. That you should expect from ANY console launch.

By "Time has Passed" I meant since Sony stated "20 Exclusives", which was like 8 months ago.

I believe MS is going to make true with all the games they announced by end of 2014, save Quantum Break. That gives them quite a few titles. Halo, Sunset Overdrive, Titanfall, D4,  Project Spark.

With MS coming with 2 very big heavy hitters next year(Halo, and Titanfall which may be a new IP but made by an acclaimed developer) Sony is going to need to show more than what they already have. Personally, Infamous Second Son is my most anticipated title by far, but most are going to need more than that for the rest of the year. I'm excited for the Order but they admittedly haven't shown much. Uncharted is about the closest they have to a Mega IP atm.

KZ and Knack at launch

January:!?

Feb: DriveClub

March: Infamous SS, MLB 14: The show

April

May

June

July

August

Sept: The Order

October:

November: Uncharted

There are some huge gaps to fill in their release calendar, and I find it difficult to believe Sony would be naive enough to think thats OK.

4 exclusives a year is plenty, they can deliver all these 20 games in the next 5 years.
