I understood that.
But again, I would point out that "minor" can still be very exciting... doubly so when "major" would inevitably involve something polarizing for the fan base. As fresh as it would be for the setting, I would not want to see it advanced if it meant, e.g., that the Eldar were finally annihilated or that the Necron threat was abated for another ten millennia (or something).
Well they are already leaning towards other races, what with the most recent rulebook pretty much stating the Emperor is going to die soon and the rest of the Imperium is falling into ruin.
I'm not sure I understand you here.
What is "soon"? The Tech Priests of the Adeptus Mechanicus discovered failures in the mechanisms of the Golden Throne that are far beyond their ability to repair. No timeline is given, though. The Throne has lasted for ten thousand years. This might not even be an issue until Warhammer 42K, for instance.
Also, I'm not sure how this involves "leaning toward other races". I'm pretty sure that, no matter what change or advancement to the setting that comes in the future (if any), it won't involve the Imperium and/or the Adeptus Astartes losing out (in terms of coverage, products, fluff, etc.) to other races.
