A brief demo of a basic sidescrolling shooter, named "Zero Gravity," was also shown, demonstrating the cross play between PlayStation Vita and the Xperia Play. Unfortunately, no price or exact date was given for access to the SDK, but Sony reps did demonstrate the ease of using the SDK for cross-platform development.
A simple animation was created using a Sony tablet, which was then pushed across a variety of Sony and Android platforms -- "No play, no life," it read. We tend to be more of the "no food/air, no life" crowd, but we'll accept Sony's statement for the sake of demonstration.
