Unless The Last Guardian really sucks or slips into 2011 (which sadly I think is possible) then for me 2010 will be the much better year. I'm still replaying ICO and SOTC fairly regularly so for me this is my most anticipated titles for the PS3 so far.
Still, with GoW3, Heavy Rain, GT5 and FFXIII (in Europe) I guess 2010 is strong whatever.
Try to be reasonable... its easier than you think...
