This is aiming to be better than HEVC, because it won't be ready for a couple of years.

Assuming the groups listed actually back up their words with action, then hardware support will happen, basically every smart TV shipped already has VP9, so if Google's Youtube and Netflix and Amazon and Microsoft agree on a codec, it'll be in hardware (both in the sense of it being available, and in the sense of it being in every video device you can buy almost instantly.)
