Honestly who cares ? Without Apple, Microsoft, Samsung and Sony on board (all are in MPEG-LA and will adopt H.265) it is dead on arrival.
I think the main reason H.264 is so popular is because of the absolutely fantastic x264 encoder. If anybody delivers something radically better (Daala promises to do) it will gain traction. See Opus. I listen only to podcasts by very technical people, and Opus took them in a storm, even without the MPEG LA.
