It depends on what you mean by "beyond"? Like what scope are we talking here.
Dawn of War and Space Marine did a lot to bring 40k to the video game community. But as for as book and film does, in its present state, not a change. 40k reads like a History channel documentary which the mainstream audience finds boring as hell. 40k does have movies: Damnitus and Ultramarines with quite plainly suck. I would love to see The Battle of Macragge done with the budget of Transformers, but in order for that so change there has to be A LOT of rewriting to be even consumable to a wider audience. So 40k references becoming as wide as Starwars or Star Trek, not achance in hell.
