I am not sure what the next patch might hold but i suspect it's extra animations.
If there was "Spare animation slots" where people could add downloaded ones could be a cool feature.
Sure they'd probably not have names of the animation used, and if people downloaded a different mixture you'd see one person doing backflips while they're seeing themselves eating or stalking prey or something but that's all part of the fun.
Of maybe there's already something like that but better in the works.
