Definitely a shame we didn't get a new ATV, but dying? Well, they keep announcing and including new channels quite regularly, so it'd have to be a very recent decision to end of life the product, and probably quite a few companies would take issue with such a decision.
Still, the lull we're in with this product is growing more painful all the time, especially when both Amazon and Google have released more feature rich products to compete against the ATV, Apple must feel the heat so when they update it, unless it's got some wow factor they might as well kill it off.
