Sony Countdown Teases Desert Game

Sony Japan currently hosts a website in which a small shadowy figure wanders through the desert. Will this be a big E3 reveal?

If you check out the site, you can pan the camera around slightly or click on the little dude to make him run briefly. The bottom left corner lists the number of days, hours, and minutes until the big reveal. Right now it's scheduled to be five days away, putting it smack in the middle of the week before E3 on June 1.

Though Sony is publishing the desert-themed Journey, it would be weird to tease a game that's already been shown many times already. Any theories on what game this might be?
