This makes it feel more unique every time when running into enemies of a different race (well, 2 so far)! It's nice seeing the new weapons randomly along with different quality as well. Will Imperial equipment get the same treatment?
Yessir!
There are http://i.imgur.com/2il2k.jpg, http://i.imgur.com/0Q1Ja.jpg, http://i.imgur.com/unIjV.jpg, http://i.imgur.com/2FHvx.jpg, and steel decorated scabbard fittings for each weapon. Some alsohttp://i.imgur.com/F1hSv.jpgfor the wealthy or high rank in the army. Weapons also have http://i.imgur.com/2qnP6.jpg, http://i.imgur.com/TweUg.jpg, or plain fullers (the center of the blade) variations for the blades...along with old versions for each weapon. So there are a lot...
This version is probably about...3 - 4 times as large as Nord, plus it comes with a small update to the visual appearance of Nord, so it should be a pretty nice deal.
As for distribution, I will designate some weapons as army issued weapons and some as civilian based equipment. http://i.imgur.com/dmodO.jpg and most of the http://i.imgur.com/ssM32.jpg for example will be for army members, while http://i.imgur.com/XZnwe.jpg, http://i.imgur.com/TweUg.jpg, http://i.imgur.com/qzMdR.jpg, http://i.imgur.com/6i5HK.jpg, etc will be found pretty much anywhere (with a small chance of being in the army too for diversity).
The legion was a bit more diverse this time around compared to Oblivion, so it would be fine (in my opinion) for variance here and there among the ranks for the equipment used.
