Anyone Downloaded An App Designed For the New iPhones Screen Resolution?

Ok just wondering if anyone has downloaded a new app for the new iPhone and then mirrored it to there Apple TV. I assume its going to be full HD resolution unlike the current iPads, iPhone 4s and iPod Touch ( untill this months iPod Touch release ) 

The reason i'm asking i can see Apple moving into more the console style gaming either by using you'r iPhone or Touch as the controller and filling the whole TV screen, which i know they can do at the moment but its not quite there with the current screen resolution.

I can just see the whole thing being taken one step further
