On August 17 the Gamescom Sony ground their own conference, the official games are currently Killzone 3 (will be revealed multiplayer) 2 LittleBigPlanet, Infamous 2, Gran Turismo 5, DC Universe Online, Journey, MotorStorm: Apocalypse and Sorcery.

But Antonio Fucito (Associate Editor, Senior Editor (Sony Area) and Community Manager of Italian gaming site Multiplayer.it) said that the vision of the events of the GameCom Sony had not yet announced a game published by SCEA (Sony Computer Entertainment America) and that was a sequel.
Warhawk 2? Uncharted 3? Syphon Filter PS3? Jak and Daxter PS3? or Resistance 3 ?
Of course it could also be a game for PSP.
We just have to wait until August 17

Don't know how credible this source is BUT if true, any guesses? My bet Warhawk sequel

For the love of god.....PLEASE BE THE LEGEND OF DRAGOON 2!

You know I haven't actually played the first one 'runs and hides before people hits me'

is it good?

ANd isn't it awesome the number of SOny titles that's being announced so far this year? it's crazy and it still keeps coming

I guess it's Resistance 3. I was already a bit surprised that they haven't announced it at E3, but of course they need something for GC to announce as well, I guess.

maybe resistance 

All the signs point to a PSP2! It techinically is a sequel.

I want it to be Syphon Filter PS3 (Uncharted 3 and GoW4 have no business being announced this early), but it will most probably be (ugh) Resistance 3. I wouldn't really want Jak PS3, because it would delay Uncharted 3, but Starhawk might be good.

It is a very good game. I would put it just under the quality of the FF PS1 games. It is pretty good.

Oh cool :D might go play the first one soon then...fingers crossed for a sequel for that also

Probably Resistance 3... But i hope Starhawk :D
