I've heard this argument a few times before but the case Kyle Richter puts forward here has me doubting myself on whether we will ever see a native SDK for the Apple TV. For me, the use case that is especially compelling in this post is the multiplayer one. Get some friends together, have all the devices connect to each other with one using AirPlay to get the visuals up to the TV. My big issue with this kind of approach is still around marketing. In my opinion, Apple TV as an accessory for an iPhone/iPad is always going to be a weaker message to put out than to position the TV + App Store as a whole new category of device.
