They say it already does: "Right now, both the Apache and nginx web servers support HTTP/2" http://moz.com/blog/http2-a-fast-secure-bedrock-for-the-futu...

The thinking is, I believe, that "SPDY/4 revision is based upon HTTP/2 wholesale" http://http2.github.io/faq/ and nginx already supports SPDY via ngx_http_spdy_module. http://nginx.org/en/docs/http/ngx_http_spdy_module.html Version 3.1 though...

So it's either there or almost there.
