For what it's worth, Engadget's original article about the Samsung press event suspected that it would announce the Samsung "Continuum" - a Galaxy S branded phone with two OLED displays. Considering the stock tickers in the background of the press image, and the fact that the secondary OLED display on the Continuum is called the "Ticker", I think this makes the most sense: http://www.engadget.com/2010/10/25/samsung-to-unveil-new-and...
The Google experience devices are developed hand in hand with Google, whereas most other devices are developed after the respective OS sources have been released.
Could this be interpreted as a call to abandon the Galaxy S ship?
