There will be no Team Eureka OTA until 1.4 posted on https://code.google.com/p/chromecast-mirrored-source/ ?
1.4 has already dropped for the kernel. Right now we are just finishing up some features, and cleaning up some code. Once we feel we are ready for a release, we will release to our testers, and if they report back everything is good, then there will be a public release.
