It seems a lot closer to h.265 than h.264, but still worse than it in all trials here. Give them another revision or two, they can probably beat it.

How do the complexity requirements compare? H.265 decoders have memory for lots of previous frames, but VP9 could be at a handicap if the format limits backward references to just a few frames.

VP10 is in active development, though I don't know how far along it is.
