I suspect the success of Space Marine II may have influenced this. I would have loved if we got old school WH40K/Rogue Trader stuff with the obvious humerous satire instead of the super-serious stuff we have now, but I suspect that isn't happening. Failing that I would like them to lean into just how miserable, dystopian and hopeless everything is but I suspect that won't happen either. I also doubt we'll get anything showing my religious extremist nutjob best boys the Black Templars purging xenos, witches and heretics (or suspected heretics, or anyone who knew a heretic, anyone who looks like a heretic, or just some passing world that caught their eye because they were bored).
As long as they can resist the temptation to make organizations heroic and show the futility of actual heroism I guess I'll be pleased.
