I'm honestly shocked that this thread hasn't been made already (or it has, and I've just missed it, in which case, derp!)! With the huge build up in the late 41st Millenium (13th Black Crusade, Tyrannic Wars, faulty Golden Throne, etc) I was curious of what the next thousand years would bring as the galaxy decends into a more desperate and dangerous place. Privately, it annoys me that Games Workshop doesn't extend the timeline (even by a little) and I was interested with what fellow fans had in mind for the future of this awesome universe.
So, with that being said, what do you folks thing will happen to the 40k Universe the 42nd Millennium? Collapse or Rebirth of the Imperium? A galaxy-wide take over by Chaos or Tau? Or just an unstoppable force/immovable object kind of battle before the Necron's or Tyranids after they've eaten or exterminated everyone else?
Post your thoughts (and preferably, the facts to back them up) below!
