The always super talented Mathias Kærlev has released a demo of the Anaconda Runtime. It was released just prior to the convention, and is a great alternative to the current HWA runtime. Features include the ability to run on Windows, Linux and Mac operating systems, GLSL shaders, the potential to develop extentions with Python, and with over 50 ported extentions so far (and it's extremely easy to port them over too with some tiny alterations to their code) it's worth trying it out.
At the convention various Nifflas games were shown using the runtime, including Knytt and Knytt Underground. All were running exceptionally smoothly.
The full version is currently unavailable, but it is finished and expected to retail for $129 USD. In the meantime the runtime demo has a watermark in the bottom left corner.
From the website: Anaconda for Multimedia Fusion 2 is a cross-platform runtime, allowing you to export your applications and games to Windows, Mac and Linux. Since Anaconda uses OpenGL hardware acceleration, it's fast, and makes effects using GLSL shaders possible.
