Horizon is the project Quantic Dream (Heavy Rain) is working on right now.

Very doubtful you'll see a reveal of it at TGS.  Expect one at an European or American game convention or exposition.

My best bet would be next year's E3.

Yep and I remember reading (don't think it was a rumor tho :S ) that the game will revolve around two people...the whole idea sounded like a romance/drama based novel come to life...I CAN't WAIT

oh yea ask CGI for any info on it....CGI = Big fan of Cage :P

man Sony has created some of the best IP's this gen(IMO) can't wait to see their other projects

most shocking news of the day :P But yea I look forward to it

He said: "There are a whole number of metrics we could measure success by, but for me on a worldwide studios side of things, there's nothing more gratifying than when we break new IPs - innovative games we bring to PlayStation fans.:

He said that it was gratifying but he didn't say that it was their barometer of success. Read it again.

I can think of 7 new IP's right now I've bought from SONY this gen. I can think of 5 right now that I plan to buy that haven't released yet. I'm not even including PSN titles.

If there's one thing SONY's doing right this gen is quality new IP's.

It's always great to hear the successes of new IP's by 1st parties that do not necessarily cater to the masses.  This helps keep gaming fresh especially for the hardcore which is whom developers need to ensure that their need are met first.  With that being said, I'm so sick of the asinine argument from some on this site who claim something along the lines of "SONY doesn't care about gaming like Microsoft does.  They let their 3rd party exclusives go.  Microsoft care more because they use their money to buy them."  Of course this twisted logic comes from the typical 360 acolyte.  Excuse me.  Last time I check if you can create something that belongs to you, it will allow you to take ownership and contribute what you have for the greater good.  That doesn't mean that every new 1st party IP will be a financially successful quality game.  What it does mean is that there will be more to offer to the gamers.  And what about new 3rd party IP's for the PS3 such as 3D Dot game Heroes, Demons Souls, and Valkyria Profile?  All of them have been successful in their own right.  But more back on topic, It's good to see SONY working on new IP's, and it's good to see them succeed. 

Is The Last Guardian a new IP?

Ok because last time jarrod was telling me that a new IP needs to be a whole new universe.

For example, he said Folklore isn't a new IP because it's in the same world as a very obscure game on the PSP (I don't remember what it was).

I think it's pretty silly. That's why I prefer the word franchise over IP.
