The Caching Server sort of already does that ( assuming that Other is iTMS content ) for Mac / iOS, but having it do that for ATV's would be brill. If there is an App store, I'm guessing Caching Server will handle apps, but streaming TV Shows / Movies would ( should ) be the next logical step....I hope they have multiple price points like the iPhone and iPad for local storage. Assuming there is an advantage. Like for gaming. Hate to always download over and over the same content. Also, for TV Shows. I might watch something at 4pm and my wife may watch the same thing again at 6pm. Why waste bandwidth. Kind of like a CACHE share on multiple ATV's.
To price the new one at 99 they reduced the current ATV to 70It will cost at least as much as the starting price of the ATV3. 130$ is much more likely.
I don't need one, my ATV3 is capable of 1080p, i only use it for streaming videos from iTunes. No other features needed.
