They're the same anyway. The helmet may look different if you don't notice the spike at the front in the one picture. But they're clearly the same armour.
You must not read a lot. Time for a revision of my original Dwarven vs. Elven armor post...
*Look closely*

Hopefully this should clear things up and you can see what I was intending to post until I realized one screenshot was actually a scan. If that second link is against the forum rules, tell me and I'll take it down (again). Maybe I'm just wrong though and it's all the same armor as most of you seem to believe.
Edit: Looking over, I noticed that all three suits are slightly different which confirms my previous assumption that either the team is still developing that particular set of armor or that it's just interchanged with other pauldrons, greaves, etc.
