So faeit212 just posted up a rumor from one of their posters and I just wanted to mention it here. I don't find anything in the rumor credible.
It sounds like random guessing since the only thing provided was:
1.) Tau will get a flyer (You don't say?)
2.) Tau will get new characters (Oh really?)
3.) Kroot might be put into a WD dex and taken out of the standard unit. (Ok, this one caught me off guard)
Anyways, I haven't been seeing any mention of the new Tau flyer as to when we will be seeing it. So heres to keeping hope alive.
