Adobe are adding their own "Stage3D" API (aka Molehill) to Flash. I realise that there are some situations where you want an "OpenGL-alike" like WebGL (especially if you're porting something already written in OpenGL). However, for most uses of 3D on the web, an abstraction layer with backends for WebGL and Flash would be sufficient, and would likely have wider browser support (it's also easier to get people to drive-by install or update Flash than Java).
