Here's the fact of the matter. It took the primarchs, plus their 10,000-man legions and supporting Imperial Army forces to take worlds. Not just the primarchs themselves. As for the primarchs themselves, Khan and Russ will be imperial commanders. Gulliman will be independent, as he does blame the Emperor for the losses not just in recent years, but for all of the tragedies and horrors commited in his name. Lion will be on the Ecclesiarchy's side for reasons already stated, while the Twins will remain unaligned. Angron will remain in the Warp until further notice, while Fulgrim and Magnus will be leading the Chaos forces. The Logar will be leading the only organized Chaos forces into the emperor's space. So it's two for the Emperor, one independent, three in the dark, and two plotting the war. Vulkan and Kurze will not return yet.
