When the Creation Kit was finally released for Skyrim on the Steam Workshop, they celebrated it by releasing a free "Official Mod" they made with Valve, http://steamcommunity.com/sharedfiles/filedetails/?id=7375. I just realized that there was never a Volume Two of that mod, unless putting Vol. 1 in the title was a gag or they actually want to release Vol. 2 when the Steam Workshop goes live for Fallout 4.
But regardless of what happens with the space core, do you think they'll do similar official mods again for Fallout 4? One for when mods go live for the Steam Workshop, another when mods go live for the XB1, and one more for when they're opened up for Sony. I don't expect them to be anything more serious than the Space Core, but that would actually be pretty neat. What kind of silly, non-canon crossovers could they do for each console?
Alternatively, how pissed would you be if Bethesda did release any silly official mods like that? I know these forums too well.
