Flash Replacement

Flash is obviously dead/dying, but I still want to be able to write online games (complete with vector animations and all). I've been studying Javascript, SVG, and some neat stuff with HTML 5. However, I've found very little in terms of a platform to tie it all together. What do you recommend?

Desired features:
* Free as in beer
* Helps with image/sound resource loading
* Helps control animation in a standard way

Box2D comes surprisingly close except for the resource loading. But it would be pretty hacky to have all screens as 2d physics environments.

Yes. Although for low level code, you will have to use something like regions, instead of full-blown GC. Also, hardware level type dispatch wont hurt, so no type declarations would be required for fixnum code.
