Ominous Futures

So what is the logical conclusion for the warhammer 40k universe? and will we ever see it? or will we somehow spiral deeper into shit?

SO, logical conclusions, I'm going to put forth 3 scenarios, that I think aren't too far off what will probably happen.

First: Crush hope of Teamwork
Humanity, Eldar, and Tau, (maybe a fourth upcoming race? we're overdue afterall! *hopes they bring back squats*) they all team up, to take down a new nid infestation/black crusade, and learn that they aren't so different after all, and humanity begins to relax a little, then they lapse right back into hatred after a darkage caused by the lapse, perhaps inventing a new chaos god (I smell a God of Remorse!! can you say emo's / scene kids?)

Second: (least likely) Epic Team up!
So again, Humanity, Eldar, and Tau team up, and they all defeat one of the big baddies. They create a new era of civility and cooperation amongst the stars...but they still fight...>.> I dunno we have to have a reason to fight, otherwise no game.

Third: (most likely) Deeper into shit!
Humanity faces an uprising of followers of the sensei emperor/ whatever other second coming of the emperor. Humanity fucks it up. They kill the second emperor. In a gambit for a coup a high ranking official tries to take his place, and further splinters humanity. Enter new faction of followers of both the sensei emperor, and new wannabe emperor. With humanity weakened, a fourth tyranid hive fleet crashes onto the scene! with two tiny splinter hive fleets too, (don't want every hive fleet to be major, need some lil' uns) with the new push of the tyranids, with crazy new units! (like... infestors from starcraft, or maybe like a new overmind collective) then chaos gets a new dex renegade Guard (just to push more shit down humanities throat) emperor's chair, totally fails, and he dies, astronomican goes out. Orks, nids, chaos, splinter factions of humanity, everything hits the fan. New Space Marines come about, to cleanse it all, playing more like movie marines, and being phenomenally over-priced.

The theme here, isn't really the end of warhammer, because, if everything ended peacefully, where would the war be? I don't wanna play in the 40k universe, when the 50k universe has been written, and we're all playing in the "past" history. that's weird! But how much more F'ed up the bum can humanity get before it just gets too unbelievable that we have clung on this long? right now we're facing the end of the galaxy, from not one, not two, not three, but four races, that are all quite capable of bringing down the galaxy. So answer me this GW, How much more can we get ourselves into?
