How far off are we from photo-realistic graphics in gaming? 10 years?

Honestly, photorealism doesn't interest me all that much. I'd rather graphics be stylistically interesting.

In the 7th gen, even Wii games like Muramasa, Kirby's Epic Yarn, and Super Mario Galaxy looked better to me than just about any high end "realistic" games on PS3/360/PC.

Hell, I still think Yoshi's Island looks beautiful, and that's running on a miniscule 64kb of VRAM.
