The first release candidate for Play 2.0 has been released yesterday! Download it here: http://download.playframework.org/releases/play-2.0-RC1.zip
Documentation can be found here: https://github.com/playframework/Play20/wiki.
First simple load tests using apache ab showed promising results: 4.000 simple "hello world" requests per second (or 7000 with http keep-alive) on an iCore 7 QC, 8GB notebook - comparable to node.js.
Time to Play!
