Yelp introduce Augmented Reality to the iPhone via Easter Egg

While I'm quite a skeptic whether Presslite's Metro Paris application for the iPhone has "AR capabilities" in the version available on the appstore, there's no denying Yelp's application does.
Found by Robert Scoble (I'm pretty sure it was leaked to Scoble), and brought to my awareness my ReadWriteWeb, shaking your iPhone while on Yelp's main menu three times, will open up an hidden feature named monocle. Monocle is nothing but an augmented reality view of Yelp's listing, as shown in the next video (many thanks to Tom Carpenter for finding this one):



It only works on the iPhone 3gs, but unlike Metro Paris, it's free, so don't hesitate to tr y it out. Now, I don't think that in the long run it matters whether Apple knew or not about this feature. Obviously, mobile augmented reality is here, and we are only about see more of it in the coming months. What should matter is what's next? Where will innovation come from, if everyone is using the same compass and GPS combo?
I for one think that we are in the middle of the "AR browsers" season, but the next big thing, which better suits the technology at hand (imprecise compasses), is mobile AR games. What are your thoughts?
