Ask HN: Will WebGL be supported on all platforms soon?

Imagine developing online games if WebGL had been supported on all platforms. That would enable rendering of 3D graphics directly in the browser without any plug-ins. Do you think that will happen in a few years? When will WebGL be a proper W3C standard, and will Microsoft ever implement support for it in Internet Explorer due to the security concerns? What about enabling WebGL by default on iPhone and Android?
