My assumption is this - with the imminent publication of Dust Warfare, the minitures rules - at least one more faction should be released during 2012, and as the world is divided into the Allies, the Axis and the SSU, the Sino-Soviet Union, I would place my bet on the Russians coming up next. I'd be quite happy if the future SSU models will look anything like the Red Blok, as I already have a sizeable army for that faction.
