The request went out to the OpenJDK community last Thursday (November 22, 2012) for Project Nashorn. http://mail.openjdk.java.net/pipermail/announce/2012-November/000139.html
The deadline for voting is midnight December 6, 2012 UTC. If all goes well, we hope to have all the bits in the OpenJDK in time for all to play with during the holiday period. Fingers crossed.
