1. not 4. Up to 6 (1920*1080)/(720*480).
2. Intra prediction of particular codec can be limited to SD resoltuion. So yes, there are some limited to SD videocodecs. Developers of x264 advise to test on HD sequences as many RD and PSY features are optimizied for high resolution and the way it's resized during degustation of encoded material.

3. Even if we discard points 1. and 2. there is still more important fact. Bandwidth (and it's main reason of my previous posts). Maybe Theora will be 'ok' for SD up to 1 Mbps. But then HD period is coming. Theora should have at least 3-4 Mbps for HD. While x264 is already good at (at least, even in future) 1.5x less bitrate.

4. I'm on side of open source and standards but considering slow development (Theora is already 7-8 years old ) and non optimistic views I don't see it's coming.
