And the teaser image:

It looks like they're showing their five biggest upcoming releases (Infamous, Resistance, Ratchet, Uncharted, Twisted Metal), without filler and Move stuff like Sorcery, which implies the other four will be of a similar caliber.

Starhawk is most definitely one, but what are the others?  God of War?  Dontnod's game?  Guerrilla Games' new IP?

I really hype the next God of War involves a new protagonist and story, centered around Norse mythology.  The soundtrack should be handled entirely by Amon Amarth!

Edit:  Bah.  I meant to change the part in the paranthetical to "5 Known", since Starhawk obviously isn't new anymore.

Okay...

Starhawk
God of War/Heavenly Sword
Agent

No idea after that.

Hoping for the first details on Sly 4.

The Last Guardian and Starhawk are two.

Are we sure that none of these are move titles?  Sony doesn't have anything move based on the site, which would lend me to believe that there must be at least one move title out of the bunch. 

As far as the four new titles?  God of War IV, Starhawk (practically confirmed), Modnation Racers 2 (big guess here), and some new IP that more or less got confirmed in another thread on this site. 

I didn't guess The Last Guardian because that ones going to be at TGS, not here at E3.  (unfortunately)

sly 4

heavenly sword/ agent/ wipeout

starhawk 

the last guardian

are my hopes 

final fantasy 7, kingdom hearts 3, legend of dragoon 2, and metal gear solid 5.....wishful thinking

I would assume if they were putting any Move-only titles up there, they'd have included Sorcery.

I suppose one of them could be a Move-only game, but it'd probably be a well known Sony IP that woudl stand up amongst those others.  Though the only one that'd fit that bill would be Ape Escape 4, and I don't think SCEA cares about it enough to include it in a teaser like this.  They didn't even publish Ape Escape 2 in the West.

PSN Defender: a tower defense game in which the player is tasked with keeping hackers from invading while simultaneously having to keep fleeing customers and developers from escaping the Store-less wasteland that is the Playstation Network.

premature ejaculation. 

I wouldn't be surprised if we see another motorstorm or GT related announcement.
