If the rumor is true than it have to be FF7,GTA or MGS 5
Nothing else will blow mind of gamers.

That's as big as a GTA: SA deal?

Come on.

hmmm...no one said it have to be for ps3.it can be psp game also.
i personaly hope for BIG new IP because these means one more great game.

If it's KH3, it's big, but not nearly as big as GTA: SA. If it's Manhunt 3 that was recently rumored... Then, not even close to being huge. Considering F13 performed very well on the 360, better than I expected (though I believe the PS3 version will have better legs), I'm not sure FF14 will remain PS3 console exclusive, I can see a FF14 360 E3 announcement.

This isnt really anything to get hyped up about. The provenance of the website isnt exactly great, and there are many other sources that correctly gussed that the GTAIV DLC would not remain exclusive. Heck, I remember PSM3 UK "INSIDER" saying that the DLC would not remain exclusive literally the issue the DLC was confirmed to be coming to 360. It's all just to get hits for their website.

I hope that was just a typo.

With popularity of the franchise, and everyone always expecting everything to be multiplatform now....I can see this as a big announcement. Sony can't really have "as big as GTA" announcements all the time. They already said that with Agent

I understand, I know it's a big franchise (first one sold over 5 million units), but I think the source shouldn't used GTA:SA big, because that's a pretty bold statement, not to mention the standard is too high.

But Peace Walker isn't called MGS5, so if there is ever going to be a numbered MGS game, it will be called MGS5.

Peace Walker quite literally *is* MGS5.  They just dropped the numeral for marketing, and from the sounds of it the franchise won't be using numbers anymore...
