Cloud gaming service for PS+ subscribers on both the PS3 and Vita wouldn't be too crazy a guess.

I think it would be stupid to show the ps4 on this years E3. Ps3 sells good compared to the other two right now. So I guess no ps4 on this e3. I think they'll show it on gamescom or TGS together with a ps3 price drop and release it right after e3 2013.

for this years e3 I'm pretty clueless what they'll show
they need to support the vita so I guess/hope they show something big for it
and I'm still hoping for a onimusha , don't care if exclusive or not I want it !

i think a PS3 Slim is on the cards, cut the price too.

like 5 different colours GLOBAL would also be good and would help PS3 sales to contiune well even if the next Xbox is shown 

Fucking hell I'm really hyped for this :D

What I expect:
-ps3 super slim at $199
-last of us stage demo
-god of war ascension stage demo
-playstation plus and playstation network revamp
-playstation all stars battle royale and lbp karting announced for vita with ps3 cross play
-call of duty vita with gameplay
-Killzone vita with gameplay
-3/4 new games announced for vita
-new quantic dream game shown
-new apps for vita

Sonys stock keeps lowering anfd lowering this has got to be a game changer for Sony, they need something big at E3 to get everyones attention. Slim PS3, maybe $50 price cut, FFVXIII, THE LAST GUARDIAN, finally releasing and price cut to Vita and some big games, new awesome downloadable software feature connecting PS3 and Vita even more. 

agent will be shown

that is all

you didn't top it

the press conference ends, the lights turn off and people are told to leave

but just before the first person steps out of the room the lights turn on and they follow a gangstar as he runs to the stage

its a rockstar dev

gta5 is exclusive for the vita

when you buy the game you will get a gun shaped usb that will have the ps3 version of the game

but gta5 only comes bundled with the vita

2 million commit suicide

Nobody will top this one: 

The conference seemingly ends

The arena is in total darkness

You here a roar like Kratos just got hit

A mysterious box appears on screen

The words "ORBIS" appear on screen

The ending of GOW3 is shown

Kaz comes on stage and shows us the PS4 (just shows, doesn't say anything)

Teaser for GOW4 is shown

GOW4 announced as a launch title for the PS4.

The PS4 itself launches next year. 

..........or maybe they'll finally announce the launch date for The Last Guardian.

You guys are doing ok with your stories, but how about something that is actually going to happen at Sony's E3 this year?

>end of Sony's press conference

>"oh, there's...one more video we'd like to show you"

>lights down, screens go black

>Final Fantasy Versus XIII logo appears on screen

>'ersus XI' suddenly turns to dust and blows away

>the numerals 'V' and 'II' merge together

>it was the FFVII remake all along

Is cloud gaming coming??? seems more and more likely
