By no way this is a comprehensive list, nor it is objective. This is just based on gut feeling, and a personal list of which games could be in my top 10 - 20 games of 2012 (plus it's restricted to PS3, the only console I own)

• Kingdoms of Amalur Reckoning: Fun combat, but the story and dialogue are presented in such a way that, I skipped thru them all the time.
• Asura's Wrath: Going to pick it up when the price falls.
• Syndicate: Solid single player, really fun co-op
• SSX: Fun trick based snowboarding game
• Mass Effect 3: Should be a solid game
• Street Fighter X Tekken: Probably the only fighting game I would have bought all year long. But still, online issues and DLC debacles ...
• Journey

• Max Payne 3: Looks technically amazing
• Dragon's Dogma: Japanese take on open world RPG !
• Lollipop Chainsaw: Probably mediocre gameplay but hilarious
• Darksiders 2: Looks good
• The Amazing Spiderman: will be released on PS3, 360, Wii, NDS, 3DS. This sounds like trouble.
• Borderlands 2: Yeap
• BioShock Infinite: Yeap
• Assassin's Creed 3: Hopefully the change of setting will finally make me like AC series
• Resident Evil 6: probably at least will be as solid as RE5, but nothing breathtaking
• DmC: can't say that it will be good
• Hitman Absolution: one of the few stealth games this year
• The Last Guardian: will it ever come out this year ? If it will, probably it will rank as high as Journey
• The Last of Us: to fill in the Naughty Dog fix this year
• Metal Gear Rising Revengeance: Hope that it's as fun as Bayonetta, also go crazy with the story
• Final Fantasy Versus 13: won't come out this year.
