I initially figured it was just a joke, but if Bethesda actually put in a colossal Queen Mole Rat I'll get a great laugh.
I don't think it will be divided up the same way skills/governing attributes were in the old games. I think they'll break it down so that you need separate perks in order to craft/modify energy weapons or guns or whatever, but then the combat perks will deal more with pistols/rifles/big guns. I mean, it makes more sense that way; someone who's proficient with a 10mm or a .32 Pistol should be able to use a Laser or Plasma Pistol about as well, but guns/energy weapons still require separate technical knowledge to take apart and build.
So, you'll need separate "technical knowledge" perks in order to craft different things like armor, big guns, small guns, or energy weapons - but in combat, it will be divided more along the lines of "you know how to shoot straight, or really swing for the fences, or handle the recoil of your weapon".
