The inevitable slip up before a Sony press conference has arrived. Eurogamer.de have posted their list of things at Sony's press conference for GamesCom. I'll let you guys dissect the info.
 
I quote:

Sony: Gran Turismo PSP, Dead Nations, Eye Pet, Uncharted 2, Heavy Rain, MAG, Modnation Racers, God of War III (am Stand)

I'm sure SCEE are delighted.
 
What do you think it is?
 

It's an unannounced PS3 game to be presented at GamesCom this year.

Dead Nations sounds like it's gonna be some kinda shooter war based thing, or RTS. I dunno either.

A mistake maybe? - that list is also very incomplete:

Maybe Dead Nations is a PSN game.

I've heard it's a PSP game. Guess we'll find out for definite tomorrow.

" @get2sammyb: Could this be Sony's answer to Left 4 Dead? "

im surprised demons souls wasnt on the list.. 
 
dead nations sorta sounds like a RTS, shooter, or a dark rpg. 

People've been saying the devs of Super Stardust HD are announcing their next game this week. Maybe it's that?

These are the people saying it's a PSP game. The site are owned by Eurogamer, and claim to have gotten word from the editor of Eurogamer.de, who broke all this in the first place.

It's a game that is being developed by the people who made Super Stardust HD.

" @Sleepy_Insomniac: Beat me to it. It looks great. Apparently the game tracks the progress of each region, so each country are responsible for the zombie outbreak of their nation. "

Looks like Hunter the Reckoning. I liked Hunter on my original Xbox so I'm down with this title, but the game also looks like another PS3 game, Zombie Apocalypse.  

Looks WAY better than those games really.  I have confidence because the Super Stardust HD developers are old school and SSHD is actually good.
 
Doesn't make me feel good that all of the recent games of that exact genre have been really horrible though.

Well I made page for it so if anybody knows some more info (I don't know much) they can put it there.

hehe, I was right! - Dead Nation is a PSN game!
