I did a search of the forum and didn't find a mention of these figures by Pig Iron Productions
They have several different "forces" available (these are the heavily armoured "system troops", they also have more lightly armored 'heavy infantry' as well as 'militia', 'rebels' and 'ferals', each with its own distinct look, as well as "wardroids" and a couple of armoured vehicles. They only thing they are missing is some sort of non-human force.
They are also offering a special package deal with the purchase of the new FW rule book. They look like a nice choice for people looking for something a little more realistic than the typical 40K figures and I may order up some of them.
