PSPfanboy has obtained a list of titles coming out for the PS3 this year and their release dates.  Of course, they are subject to chage, even if they are correct, which is why this thread's title says rumor in it.

But here they are:

The full list is here...  Click my Linky

Metal Gear Solid 4: Guns of the Patriots release date from gamestop.com is lookign more and more likely now that best buy list says the same thing.

Killzone 2 not delayed? Neither LBP? If this is true, PS3 owners should be very happy.

GTA IV - 1st of April
Haze - 18th of March
Killzone 2 - 7th of April
LittleBigPlanet - 7th of April
Rainbow Six Vegas 2 - 11th of March
Devil May Cry 4 - 4th of February

Those seem off.

Huzzah!

Looks good, but I doubt Killzone 2. The hype would have been re ingnited if it was only 4 months till launch. Anyway, how long does it take to do a beta?

I think many of the games seem fine except for Vegas and Killzone which we haven't seen much of lately, but the rest seem like the right time frame.

Haze was supposed to be out now, so it doesn't seem unlikely it was only pushed back three months. GTA is in the quarter take two said it'd be in. MGS4 in June is also on GS website, DMC4 comes out in JP this month, so next month in america seems likely. Burnout is confirmed, I think the list is somewhat right.

Bah... nothing on Socom Confrontation yet. I really want that game sooooo badly!!!!

 With Vegas' initial announcement they said march, although we can safely assume that it will be pushed back, the last one was by 7 months, I still bought it and loved it

One thing I noticed was Two worlds...thought that was 360 exclusive?

LBP, KZ2 and GTA4 released within a week of each other. It is like Christmas in April for PS3 owners.
