Now let's break down these lists. There were 67 total games announced for PS4 since 9/1. Of those, 48 had no mention of an XB1 release on the developer's website or social media channels (one of them being first party/Sony published, bringing it down to 47). If we were to take out all Playstation Experience related announcements, if the argument were that those titles would only be announced for PS4 at that time since it was a PS exclusive event (despite the fact that two of those PSX announcements were also announced for XB1), that still leaves 34 titles with no XB1 release plans announced.

On Microsoft's side (which were considerably harder to get since MS doesn't have an official blog style channel for ID@Xbox, so I had to cross reference all titles announced on the PS Blog and use fan sites like Pure Xbox and others), 24 games were announced. Of those, four had no mention of PS4 release plans. We can most likely nail down two of those titles as XB1 exclusive as they're Kinect only (Boom Ball and Infinity Blade). How, exactly, is the parity clause helping to bring exclusives to XB1 again?

(EDIT: Numbers adjusted a bit. Grave was announced for XB1 at E3 (thanks Miles), Commander Cherry is also coming to PS4 (thanks Banjo), We Are Doomed is also coming to XB1 (thanks ID@Xbox), and the Banner Saga is also coming to XB1. let me know if I need to correct any more!)

Ninsect edit: Added Dungeon Defenders 2 to PS4's list.

Downplay incoming in 3, 2, 1...  wait what the.  Samus we're supposed to do it on 1!  

Pfft, those are not games.  Only AAA exclusives that are not ports or remakes have any value don't you know.

those are coming too and PS4 already outnumbers it on retail exclusives.  Don't blame Sony for your extremely narrow tastes.

This does not include first party/big 3rd party games, obviously. If it did the difference would be even larger.
I'm very sorry that you have such limited taste in gaming though. 

Too bad none of these games are games.

I'm glad I can have fun without paying $60. Personally I'm interested in getting the following games on my ps4 or vita from that list.

RIDE

Costume Quest 2

Retro City Rampage: DX

Terraria

The Banner Saga

Distance

Rocket League

Killing Floor 2

Bastion

Orcs Must Die: Unchained!

Shovel Knight

Super Time Force Ultra

And that's just the games that I've actually heard of so can make a judgement. I thank god everyday for giving me the ability to enjoy a variety of games. As a nintendo fan I would have thought you'd appreciate that GAMEPLAY is what matters more.

Xnone?

To be fair PS4 already have close to twice games than Xbone... and third will focus on PS4.

MS will only moneyhat some exclusives.
