Well, the Tau are out of the bag.

Both 3++ and Faeit 212 are reporting that the confirmed release date will be April 6th for the new Tau wave. While I will hesitate to call it confirmed (who confirmed it?) I don’t doubt that it is happening.

That leads me to the Kroot- it appears fate of the bird warriors is still up for debate. Faeit 212 reports that a new allies supplement is rumored for later this year and that Kroot will be part of it. So the question remains, what about Kroot in this new Codex? Faeit points to a few rumors from last year.

Kroot and other existing allies are there, however they are limited. There appears to be an “Allies” supplement which will be out about the same time and include many more options. (aside: Dare I start a Spring of Allies moniker…ah well then it will end up being 2 years from now… )
My sources are telling me kroot are in fact still part of Tau, and have a new unit or two including a beastly transport. They may have more options in a later supplement.
I also checked into the demiurge rumors, and was told “There are no demiurge in the Tau codex.”

I myself am a fan of the Kroot and would hate to see them left out. Right now we are all just holding our breath for the official release.
