For me its Kratos. That dude is BRUTAL.

If its current mascot I would say Rachet, since he's a likeable character and he has a cute look. Back in the PS1 days I could say Crash Bandicoot.

Crash Bandicoot, closet thing they ever had probably followed by Solid Snake.

Kratos and Drake.

Solid Snake has had games released on every Sony video game console, I think that pretty much ensures his mascot position.

I guess Solid Snake, followed by Kratos, followed by the Ratchet and Clank dudes, but the real answer lies here:

I don't think they have one. 

Sackboy.

solid snake, lets face it, when you think of sony, you think of metal gear solid

I still feel like it's Crash. But, besides that, probably just Ratchet or Daxter. You can't have people dressed up as Solid Snake or Sackboy. That's just creepy, or scary. A giant Daxter might actually work. The only problem is that no one knows who the hell he is. Even more simple: there doesn't need to be a mascot for each system. The PS3 seems to host more mature games, and it would make sense that it doesn't have some big fluffy Otsel walking around shopping malls.

IMO, no one yet. If you think about it, no one has the mainstream recognition or universal appeal that Nintendo mascots like Mario and Zelda have. No one as famous as the Master Chief for Microsoft. Don't get me wrong, they have great characters and games, just no one as a mascot yet, because none of their characters have mainstream recognition yet.

GIANT ENEMY CRAB.  There is no other.

Kratos. That's the only character continually receiving Sony's love.  "

Kratos, Ratchet, Sacboy, maybe jack, sly, crash, spyro, are all i could think of right now.   
 
M$ has master queer : ) and thats about it. 
 
Nintendo has anything Miyamoto.

Sackboy is very mascot like. They kind of blew an opportunity to really install sackboy into the mascot position by not working it into other games like Modnation or Home.

To be honest, I don't see Sony nor Microsoft having a mascot at all.

The buttons.
 
They've pretty much used the buttons as their abstract mascot for a while.
 
And lets not forget Toro!

Maybe some Final Fantasy? In the US market, I'd probably gun for Drake and Kratos right now. Maybe some Killzone 2 or Sackboy action.

the system is its own mascot. it only does everything.

im pretty sure Kevin Butler is the current Sony mascot... or he is to the masses 

Nintendo Entertainment System -1985
Mario - Early 80's
 
Microsoft XBOX -2001
Master Chief - 2001 

Sony Playstation - 1995 
Kratos - 2005
Sackboy - 2008 
Drake - 2007
I don't see how your company's mascot can manifest that late in its history.

Probably sackboy, but they don't have a real mascot. At least not one that is immediately identifiable with the company like Mario, Sonic, or Master Chief.

Kevin Butler > Kratos

" If its current mascot I would say Rachet, since he's a likeable character and he has a cute look. Back in the PS1 days I could say Crash Bandicoot. "

I would actually love to side a proper forward platforming Crash Bandicoot again. It was this weird hybrid when people were leaving 2d and didn't know how to hand 3d, and you got this weird sort of forward moving sidescroller. Bring it back.

a giant cock pissing on other companys saying i win

The only thing that comes to mind is Crash or Spyro from the PS1 era.

They'l probably make sack boy the mascot now that they own the studio. Its hard not to like him tbh.

A Nissan Skyline GT-R.  Have been with Sony due to the GT series and that was what got me on to the PS3, anticipation of how good that game can look in HD.

Sackboy.
