I think it would be interesting to do a follow-up comparison h264 vs VP8 for mobile. 1080p vbr targetting ~7 Mbps, 480p vbr targetting ~2.5 Mbps, etc. It's imp

  I think it would be more interesting to compare VP9 with HEVC (h.265), I know the VP9 experimental branch can easily be checked out and tested, but I don't know of where to find HEVC encoders (although I'm sure they exist with some Google fu). Obviously there are problems with testing unfinished implementations, as: A) they are generally VERY slow given that there's little optimization during the development phase, and these next gen video codecs are more demanding than the previous generation B) a great deal of the quality comes from fine-tuning during implementation, not from the specification. For example x264 is a 'best-in-class' implementation of h.264, readily beating many other implementations of the very same specification. As such, this fine-tuning is not likely to exist until the codec implementations mature, which likely means that what is available now of HEVC/VP9 serves only as very rough estimates. Would still interesting though :)
