More is coming next week, and one of the hints obviously points towards the Onager Dunecrawler, which is a very likely candidate for pre-orders next Friday. What else it means?, I'm not quite sure, but hopefully we will see two more kit releases for the Skitarii.
Please remember that these are rumors until verified by leaks or official announcements. Both of these bits come from Warseer forums from two people with the White Dwarf in hand.
Btw next week will be.....
weapons of skitarii
what is waiting in the dunes"
in the WD they talk a little of the other Mechanicum factions that sometime fight alongside the Skiitari, they cite by name the Titan Legions, the Decurio Ordinatus and the robots of the Legio Cybernetica.
