What things would you like to see become available to unlock in the Krypt? Weapon skins, fatalities, arenas?

Personally, and it may sound odd, I'm hoping I can unlock some cool concept, fan art, other sketches of character, areanas, and others. i guess it kind of started in Mission Mode from Soul Calibur. I thought the art work you unlocked was pretty cool, especially since some of them rewarded you with outfits and arenas as a bonus. That's what was a little dissapointing for me in Soul Calibur II. But I'm getting of topic.

I'd like to see some of those parody adds they had in DA, you know, like Kano O's or Nitara's blood energy drink, those were pretty funny.
So aside from characters and arenas that will be unlockables in the game, what else would you like to see inside?
