I'm not seeing it.  I went back to look at 2011:

LBP2 - January
KZ3 - February
MotorStorm - March
SOCOM 4 - April
InFamous 2 - June
Resistance 3 - September (6th)
ICO & SotC HD - September (28th)
R&C All 4 One - October
Uncharted 3 - November (2nd)
EyePet & Friends - November (15th)

It's possible that I've missed something but that still looks pretty darn spread out to me, especially considering that was one of Sony's best years in terms of total content.  I will concede, however, that EyePet & Friends might have cut the legs out from under Uncharted 3.

Except only half of those were sony released games, the rest third party. Oh and you know 2010-2013 is 4 years.

Sony is delaying games because they were never ready and they have no need to rush them as they are winning, there is no secret strategy behind their logic, but I don't think anybody here will convince you otherwise.

Ok, how many of those flopped? Motor Storm, SOCOM, EyePet & Friends all flopped. Infamous 2 and Resistance 3 didn't do too well either compared to the games before them. 

Ok, lets try 2012: 

Twisted Metal - February 

Journey - March

Starhawk - May

Little Big Planet Karting - November

Wonderbook - November

Playstation All Stars - November

Ratchet and Clank - November

Doesn't seem to be spread out well at all after May. Twisted Metal, Starhawk, LittleBigPlanet Karting, Wonderbook, Playstation All Stars all flopped. 

All of those are exclusives pal. All by Sony own studios. And we can make wager right here right now that WILL NOT see Sony over saturate first party releases EVER during this Gen. And you will also see incredibly greater sales for first party games because of it.

Um, Nintendo couldn't afford to take that strategy because they arrived to the HD generation late, Wii had lost all momentum and third party support and they had something to prove. They haven't so far. Sony is selling PS4 off it's technical prowess alone (it's the most powerful console ever and it sells for one incredibly competitive price; amazing value) right now. Also gamers are well aware of Sony's track record of releasing myriads and myriads of diverse and quality exclusives throughout a generation ALL THE WAY THROUGH THE GENERATION AMD BEYOND EVEN. Cant compare Sony and Nintendo in that regard mate. Not even close. 

I'm really not sure what you're trying to say anymore.  MotorStorm flopped because of REALLY bad circumstances, SOCOM was a bad game, and EyePet & Friends ... really?  What is your point, though?  That spread-out games can flop, too?  They certainly can, as we can see with StarHawk and Twisted Metal.

And no, I refuse to count Wonderbook for anything.

What I'm trying to say is that Sony was releasing too many exclusives every year. I was agreeing with the OP, that it was a bad business decision by Sony. They weren't properly marketing their games because too many were being released. In 2011, an exclusive each month meant that some of the games flopped cause they couldn't compete and they weren't marketed properly. 

So true. For years the gaming industry has been making a gross error by not releasing during te summer. So many kids outta school starving games. College students like me no classes. And let's not leave out since NO ONE WANTS TO RELEASE IN SUMMER the window is WIDE OPEN lol that's how Last of Us dominated. Well, that and it being a frickin' masterpiece and all.
