Hey all. I considered throwing this into the rumor thread, but I figured it belonged here instead, since there aren't any real rumors, only conjecture.
So, a friend of mine is convinced beyond reproach that the vanilla Space Marines are going to be the ones that get the update for 6th edition as the first book that comes out. The reasoning is simple... it's what GW has always done. Now this friend is a staunch Imperium-lover, so it's no surprise that he'd literally scream 'heresy' at the idea of Chaos Marines or something else being updated instead.
But my question is... considering the rumors we've heard, and how inconsistent some of them seem (different rumors at different times keep changing the release schedule around), how likely could it be that GW pulls a fast one and releases 6th edition with vanilla Space Marines as the first Codex? They are indeed the poster child, and they have been getting the first update for the past few editions, but what's really the chance that they'll be the first updated, yet again?
