As of right now I see Super Mario Galaxy, Wii Sports and possibly Mario Kart Wii for the wii as classics.
For the ps3, it is hard to say but I think GT5 will become a classic, like GT1 and possibly GT3 and God of War 3 (that puts a nice end to the series, thus making all three classics).....if no other god of war comes after it. I would say LBP, but I know LBP2 will come out and it will be much better.
For the 360, I can't really pick out something that I would say ten years down the line....that was a classic and this is my most used console. In terms of exclusives I can't really think of one, maybe if I was a huge halo fan, I would say Halo. I do think tales of vesperia will be my own personal classic.
Portal, I think will become a classic, hell the whole orange box. Fallout 3 should become one and Call of Duty 4. Same with starcraft 2 if it is as good as starcraft.
