It will depend on the general consensus of this site in the end of this generation. For me, it will be very difficult to top what Demon's Souls has achieved this generation, so far it's the game of the generation, along side Lost Odyssey, Dissidia and Super Mario Galaxy.
The only ones I can see challenging those spots are Mass Effect 2, Parasite Eve 3rd Birthday, GT5, Lufia 2 remake, Final Fantasy XIII and Final Fantasy VXIII.
