Google TV bombed and Logitech had to reduce the price of the revue by 200% because Google didn't release the SDK in a timely fashion. It took years. Lets hope they don't repeat.
There were all kinds of reasons that Google TV bombed, least of which was the non-release of an SDK. They should have partnered with a content delivery company, like DirectTV, and not a peripheral company like Logitec. Also, the price was out of this world, for what you got.
