Microsoft will support VP8 in IE9.

Apple's HTML5 implementation uses Quicktime, so supports any format for which you have a Quicktime plug-in. I have no trouble, for instance, watching Ogg Theora video on HTML5 sites in Safari on my Mac.

I'd expect that Perian will add VP8 support for Mac, since they already have a couple other codecs from the VP family. Perian is a third party collection of codecs for Quicktime.

When people ask about Apple's support, I think we can assume they're thinking of the other two platforms, which will not run QuickTime plugins.

Microsoft is already on board. Apple not so much, but pretty much everyone else is behind it, so Apple may eventually be forced to accept it.

I doubt Apple will cooperate with Google. On the other hand, if YouTube drops support for H.264, then Apple really has no choice. I don't know how much money Google makes from YouTube mobile, but if it's not much, they can really screw Apple over if they want to. Who's going to buy an iPhone if it can't use Youtube or any other online video site?

I am. Online video on mobile is something I can easily do without.

So I assume you torrent your porn and transfer it to your iPhone directly then.
