This image (below) was sent in to clear up the confusion, and brings about more questions for me. Is this what we will be seeing this month?, it does not appear to be so, as Genestealer Cult mini's seem to be at the center of this months release. Regardless I am excited for this game, and this is definitely on my list of things to get, especially when the Rogue Trader boxset comes.
So possibly its like this. (me speculating a lot, so not even a rumor here)
Kill Team Rules released in July with a couple factions possibly in a boxset... Genestealer Cults vs (skitarii)?
Kill Team:Rogue Trader will come out later this year. Future Kill Team releases will be like campaign box sets with two new forces.
