I doubt an Apple Television will be anything mentioned by Jeremy Allaire.
Apple is about simplicity. The Apple Television will be a 100% wireless device.
The Apple Television will simply be a big screen to hang on the wall. Just like hanging a picture frame. No cables, no wires, no connectors. It will be 100% wireless - even the power.
From July 2011 - Apple's Interest in WiTricity Wireless Charging

It will pull data from the iTunes Cloud or your own Mac/iOS device. But it will have zero connectors on it. No ports, no HDMI, no Thunderbolt, no nothin'. It will simply be the largest screen in the house you can blast anything you want to from any of your Apple products - in HD. There will be zero configuration. Power will use the wireless electricity charging by WiTricity so there will be no need for even a power cord.
I think this is why it is taking Apple so long to bring a television to market.
It's going to change everything.
