Anyway, they're up for pre-order now from the 40k website.
From the announcement:
Knowledge Is Power.
Merciless and pure in their search for data, the Skitarii - soldiers of the Machine God - march without emotion across the galaxy, tearing the secrets of war from the cold, dead hands of their enemies. Armed with the most terrifyingly advanced weaponry the Imperium has ever known, and driven by data imperatives that enhance their abilities to almost supernatural levels, the Skitarii are a post-human nightmare rendered in metal and flesh, collecting and analysing every morsel of information they can in order to fuel their thirst for ever more powerful tools of destruction.
This 80-page, full-colour hardback book contains:
A detailed, full background on the Adeptus Mechanicus, with information on forge worlds, motivations and history of the Skitarii and timelines giving you the lowdown on their place within the universe;
Descriptions of the armed forces, vehicles and technologies of the Skitarii, with rules for each;
A stunning showcase of beautifully-painted Citadel miniatures, with colour and iconography guides for every forge world faction.
An Appendix detailing warlord traits, wargear and the Doctrina Imperative - a rule allowing Tech-Priests to remotely boost soldiers’ abilities from their observing scryships
Initially an elite assassination squad, the Sicarian Ruststalkers proved so effective at the art of killing that they were repurposed as front-line, physics-manipulating commandos. Their transonic weapons hum and resonate with sickening efficiency, passing through the strongest armour as if it simply didn’t exist.
The box contains 5 different, cybernetically augmented gasmask-clad Sicarian Ruststalker heads, covered in sensors and data-gathering devices to further the quest for knowledge. More machine than man now, their bodies are encased in pressurised armour. An impressive array of armament options include two transonic blades each, or a loadout of chordclaw, transonic razor and grenade pack, making a total of twenty-five included weapon parts. Their princeps includes a prehensile dataspike.
This 117-component, multi-part plastic kit contains all the parts necessary to make either five Sicarian Ruststalkers (including one princeps), or five Sicarian Infiltrators, and comes with five 40mm bases.
Now more machine than man, the Sicarian Infiltrators are a hideous, frightening strike force - the height of Adeptus Mechanicus posthuman engineering. Enemies fall, deafened and blinded by the scree of a brutally disruptive audiovisual assault; battles are often decided before even a single kill is confirmed.
This multi-part plastic kit contains all the parts necessary to build five Adeptus Mechanicus Sicarians - either Sicarian Ruststalkers or Sicarian Infiltrators, including one princeps. Each model features extensive body modification - flesh has given way to machine, and what little remains is encased in pressurised armour. Sensors, pressure gauges and data arrays cover their surfaces, and an included five sets of legs add a variety of posing options, making your squad truly your own.
The Sicarian Infiltrators are the scout class; almost their entire human heads have been replaced with an intricate domed helm allowing a three-hundred and sixty degree view of the battlefield. Two weapon options are available to each model - ten sets of stubcarbine and power sword, or ten sets of taser goad and flechette blaster; a total of twenty weapons in the box. Their princeps carries a stubcarbine and power sword, with an included infoslave skull - every movement recorded and analysed for the optimisation of battle.
The box contains 117 components, and is supplied with five 40mm round bases.
