You can still get to the product info. page, but it was featured on the main page. It should be released any time now, so I guess it is no longer being pushed?
For $99 I cant see them killing it now. It easily replaces the Nexus Player for the price point with full Ethernet support and 16GB storage.
It's still there, go to Products -> Systems.
With how long it's taking to get to market, and the shield TV, there is very little wind left in its sails.
