One thing I'd like to know is when and where these new husk varieties will appear. Seems to me like Earth is the first place the Reapers attack (assuming the attack is in fact a surprise), so the majority of husks would be human. But if other alien husks are present, then that would mean other planets were attacked and no one knew. That might be possible considering how the Collectors operated, but they hit smaller colonies and even then the galaxy was aware of the attacks soon after.
