So I've just picked up my Tzaangors and I'm surprised that there are no instructions on how to assemble the sword and shield versions, or any of the AoS options (banner, horn, huge sword and huge axe).
That says to me that there will be an AoS version of the Tzaangors box at some point, maybe without the 40k sprue.
Also, due to the number of the special weapons you get per box, looks like they'll be 1 per 5 which is quite nice.
