I expect that Blizzard will open up these skins one day, now that those dwarven factions have been pulled into the Alliance. There isn't a very good mechanical reason it couldn't be done. However, I do suspect it's very low on Blizzard's priorities. It would be a purely cosmetic addition, and it would pull the artists away from doing things like modeling armor and mobs for future dungeons and raids. It would be awesome to roll a Dark Iron, but given limited resources, we would probably rather have cool-looking armor instead.
I was writing a short story with one of the main characters being a deathknight when something stopped my in my tracks, it was silly and taken for granted but I want to be correct as possible... do death knights need to eat?
According to some books up in Acherus, death knights don't need to eat to survive, but they certainly can eat. Personally, I would guess that whether or not death knights bother to eat depends on how close to their old life they feel.
Are they bitter and resentful of the living because of what happened to them? Then they might distance themselves from the living and stop doing things that a living person would do. They might embrace death and all that comes with it. However, a death knight who misses life and still has living loved ones they hold dear might cling to what it is to be alive. They would still eat and drink even if it didn't benefit them at all because they enjoyed it and still want to enjoy it.
Does the PTR patch itself like the game client? Or is every PTR a completely new download? Wondering if I should erase the whole thing or expect it to patch itself up to 4.2 when that PTR starts.
Usually the PTR client patches just like the live client, so you benefit from not deleting it. However, there have been times in WoW's history when you had to do a clean PTR install. That hasn't happened in a while, though.

Is writing for WoW Insider a job or a hobby? If it's a job, is it the only job you have?
Our staff is very diverse. It's a job for some, and it's a hobby for others. The editors (if you don't know who we are, check out our About page) spend anywhere from 40-60 hours per week on WoW Insider, depending on what's going on that week. This is our primary job. We all have side jobs because that's just how it goes when you work freelance (not having all of your eggs in one basket is just good judgement), but WoW Insider is our main focus.
Our weekly columnists are the ones most likely to just call it a hobby -- the guys and gals who turn in their column once a week and leave it at that. They all have jobs outside of WoW Insider, and this is just a side gig.
