Wow that is amazing. What he is saying about it as well has long been a dream. I hope WebGL can do for 3d content/games what Flash did for video when youtube hit. Easy, accessible, fast loading content:

Mark DeLoura: I think Flash will continue to be a very viable platform. The Flash toolset is pretty frickin' amazing, and there are a ton of happy Flash developers out there, and great games galore.

I would like to see higher-fidelity 3D content on the web though. It's been a dream of many people going back to VRML days. WebGL and Native Client are two solutions to this that will be integrated into the Chrome browser. At Google I/O we talked about Unity running inside of Native Client, which combines the hardware acceleration and security of Native Client with the fantastic toolset and runtime from Unity. It's peanut butter and chocolate (well, for me). :) This is a platform I'm really excited about for 3D web games.
