It will be interesting to see what happens with VP8/WebM. Really it looks like Google tried to stymie Apple (which committed itself to H264) first by trying to back Adobe/Flash and then VP8 (and announcing that H264 support would be dropped from Chrome, which AFAIK it hasn't been on any platform). Thus far I don't see VP8 achieving much and Google may just end up sticking with MPEG standards.
