its pretty clear from posts by Aaron, Patrick, CanRay, Bull, and Hardy that they are aware of the need for an errata, and they are working on it, but you would have to read through dozens and dozens of threads to know that. (it's not been a central topic posting but spread all over the place).
As for an ETA, I am going with my gut ( and keep in mind, I am not employed by Catalyst, nor have any advanced, "inside" sources) and think that you can expect a Errata to be published sometime in the new year.... but most likely closer to March 2014.
That, of course is if they do not decide to release the errata in the upcoming sourcebooks based on topic. Meaning the Magic errata in the magic sourcebook, the Rigging errata in the riggers book, etc..
