In Hâkon Wium Lie's latest missive on Opera Labs he details Opera's upcoming support for the <video> element in HTML 5. He points out that it's not much use without at least one defacto standard web video format (much like JPEG, GIF and PNG have become for the <img> element.

A preview release of Opera 9.5 includes native support for Ogg Theora (the free video format from the people that brought you Ogg Vorbis and Ogg FLAC) -- which to me seems to be a step in the right direction. The current preview is Windows-only, but Theora's LGPL library is widely supported cross-platform, so Linux and Mac previews are surely not too far away.

HTML 5 similarly includes a <audio> element. Will the other Ogg formats see native support in Opera?

In other news, Opera's internal builds implement CSS text-shadow. See Rijk's blog.
