After earlier's post about where the Tyranids are, I have had another confirmation that they are indeed coming. So we should start hearing something very solid with more breaking detail here very soon. A few more deep breaths guys, and we should have more solid information.
On this site we have had more than one (several in fact) very reliable sources confirm them coming. So as far as I am concerned, there is no need to worry about whether or not they are coming........... They are.
The Lictors are here lurking in the shadows.
