The current target date for the open beta is Jan 16th. We've actually open sourced the new set of code already, you can see it on github.
Any update on this ?
Yes. Jan 17th
In all seriousness we're pretty close to ready. We've got a nice interface this time too, thanks to our new intern Seve. We've committed to not sleeping until we're ready to go but midnight seems a bit optimistic.
