How much better is VP9 than VP8?

It seems as if VP8 was just released, and now VP9 has been announced by Google. What advantages does encoding video with VP9 have over VP8? Will it be worth the effort to switch?

Much better, at least when it comes to bandwitdth. According to Google, VP9 uses 50% less bandwidth for the same quality of video. So, yes, I'd say it is worth the effort. C/net had an article about it earlier this week:

VP9
http://en.wikipedia.org/wiki/VP9

"VP9 has many design improvements compared to VP8.[1][2] VP9 will support the use of superblocks of 32×32 pixels and the developers are considering adding support for superblocks of 64×64 pixels.[1][2] A quadtree coding structure will be used with the superblocks.[1][2]
VP9 will have a separate feature-set, which will be optional for hardware, that is capable of 4:4:4 chroma subsampling, alpha channel support, and depth channel support.[8] A feature-set is signalled using a version/profile flag.[8] A feature-set that supports a bit depth of 10-bits per color is under consideration.[8]"
