From an Apple TV reality check
I believe Apple TV’s magic will be performed by a separate box, a descendant of today’s $99 Apple TV black puck, perhaps in combination with a new version of Time Capsule. This will enable the no-longer-a-hobby Apple TV to bring its magic to the millions of HDTVs already in homes all over the world — and to be replaced with better/faster hardware without drama.
(While we wait for the grand new Apple TV, we’re likely to get an updated version of today’s black puck Real Soon Now: The vintage 2010 model is no longer available online at Amazon, Best Buy, or Radio Shack — I just checked. If, as I hope, the upgrade outputs real 1080p HD — 1920 by 1080, versus today’s 720p — 1280 by 720, it’ll be an easy sell. Especially as an AirPlay companion to something like an iPad HD with twice the linear resolution of today’s tablet, 2048 by 1536 versus the original 1024 by 768.)
