A Phone Game System?

Phones are getting more and more powerful. With the 64 bit A7 in the iPhone 5S, and the powerhouse processors such as the Snapdragon 800/801 and the Nvidia K1 along with the hundreds of custom-superpowered ARM chips bursting on the scene, I'm wondering if we need the dedicated indie-consoles like the Ouya. It's hardware is a year (or 2) old, and they are mobile components. What if there was an app that turned your phone into a TV/screen optimized game system with it's own app store and you connect the phone to a special dock that has it's own game controllers and outputs at 1080p via HDMI? Tell me what you guys think.
