Oh, the article doesn't explain it very well. Both of those people are related to Capcom, and Capcom is... yeaaaah. Let me try since they've elaborated on this quite a bit on another forum, since a lot of people had the same response as you.
First of all they are basically paying 8 staff members just above minimum wage for over 2 months. That's the first $48K. There's a list of their staff somewhere out there but IIRC it'd be really hard to call it bloated once you saw it.
The Animation Contracting is because due to the game's art style they need 1500+ separate, high quality drawings done in a timely fashion. Lab Zero's art people are either working with the contractors or contributing to the cause themselves. Or doing clean-up or whatever it is artists do.
For the hitboxes they're contracting the dude who did them for the past 8 characters. You have to do them by hand if you want them done right, and each frame in Skullgirls has quite a few hitboxes for accuracy. So that's 1500 frames where the dude has to go through and carefully add in all the hitboxes. Say it takes him two weeks to do a perfect job. That's $2k of wages right there.
'Course, then you have $7K eaten up for the voices - I have no explanation for that one - and another what, $60+K for QA, fees, and rewards?
So yeah, most of it is either miscellaneous stuff or art. Apparently they have more stuff to do than the DLC, too, like the PC version and other stuff. Thankfully they aren't charging for the DLC, which is good since we're more or less paying for their existence.
