Well well well, whataya know? I have, through
If your net-foo is strong, you may find it too.
It's an incomplete scan of what looks like a pre-print test copy. It includes the detailed unit descriptions and the army list section with all the costs, but does not include the summary sheet or individual weapon descriptions. Did GW leak this thing on purpose? Who the hell knows. But if I was going to leak something on purpose, this is how I would do it.
My reservations about the number of competitive builds has abated... somewhat. Farmpunk and I think there will probably be 2 strong 'Pure-GK' builds (IF the Psycannon is S7 Rending Assault/Heavy 4 as rumored.). To which I think you'll be able to add 1-2 pure Henchman builds and 1 mixed build with a few minor variations.
But apart from that, I'm seeing a lot of potential here for running an AdMech (or Tzeentch) army using the GK rules. The key is the Henchmen Options. Coteaz makes them troops, and they're highly customizable. So there's your Skitarii. Mix and match as needed. Add some elite Marines and battlemechs to taste. :)
