(Although I think Safari and Chrome have some support for the Ogg > video stuff.) No. Safari doesn't support Ogg at all. Safari and Chrome support H.264, but Chrome supports Ogg. Apple won't support Ogg since there is no hardware support for it which makes it difficult for Mobile Safari. You can support both Ogg and H.264, but you'd need to generate both videos. John Gruber talks about converting H.264 to Ogg and setting up the video tags. http://daringfireball.net/2009/07/ffmpeg2theora If Sage ditched compatibility for Safari, you'd lose any iPhone/iPod Touch support. I'd prefer to avoid the use of Flash for the same reason. I don't mind the use of the video tag, but ffmpeg can generate H.264, but apparently the Ogg support is problematic. Hence the ffmpeg2theora.
