We haven't even rendered a perfectly realistic scene yet, let alone rendered in real-time. For a real-time rendered scene with a human in it to look identical to real life, I think we need a little over 5 years, and there's plenty of problems (like animation) to get over.

Bet with disolitude: Left4Dead will have a higher Metacritic rating than Project Origin, 3 months after the second game's release. (hasn't been 3 months but it looks like I won :-p )
