LOLOL, Agent is in such a shroud of mystery right now!

Do you think we will see it? Like ever?

The Legend of Dragoon 2 with cross platform play between Vita and PS3.

I want you to be right.

Maybe it's Syphon Filter? Or maybe even a normal Ape Escape game maybe?

I wouldn't be surprised if it were cancelled honestly.

not sure what it could be. i was reall worried what Sony would have 2012 holiday season, but now i think i get the big pictures.

Halo 4 on COD wk is still huge for MS but god of war seems to be the start of something big for Sony with medal of honor.

my mind is somewhat at ease but i still need something that will stop the second guessing.

It'll be a playstation Mini

GOW:A will be released next next year, so they are making hype.   April 30th there will be another event for the game which most likely I think will show some in-game footage, and by E3 Sony will end the conference with a demonstration of pure gameplay of a never before seen part of the game (till that date).

This new exclusive by the looks of it can be a 3rd Party exclusive (jeff likes to emphatize when sony is involved).  But if not, I think it will be the fighting game from Sony.

E3 will be where The Last of Us is going to be shown in a massive way  with lots of gameplay demonstrations.  Probably the E3 will begin with it.

Also on E3 Sony most probably will show lots of Vita stuff, so they are showing PS3 games earlier so that they have space in the conference for the VITA games.   

PS: Also they could bedoing all this things because, maybe, they are going to announce a price cut soon; so they want people to get HYPED with all the AAA games coming and when they announce the price cut, all that people will desperately go to the nearest store to buy their PS3 :D.
