Yes. In this thread - the new Hive Guard models. Go back a few pages
Yeah I posted the image up of Hive Guard box a while back, which wouldn't surprise me if it was a dual kit for Tyrant Guard also. Though I like the fact not everything is being leaked, admittedly we still have a month or more left to be leaked, but it's nice to have genuine surprise regarding a new release.
Regarding it being pushed back until January, that makes me happy. I never wanted a December release because that would have been when I have no money. So January is better for me, not that I was going to buy much because my 'Nids are fine but I don't expect the new models will be cheap :-P
