I don't remember hearing an official release window for FFVXIII so I don't think it can be delayed. That said, I too don't expect it to be released in 2012. What about The Last Guardian? I don't think it has a release window either? Anyway, I think it's coming this year, in Japan at least.
Mass Effect 3 is probably coming this year, I think BioWare know what they can do. I also don't think Zelda is going to miss 2011.
Even Duke Nukem Forever is coming this year, maybe many games won't be delayed this year =D
