What i think it is:
On your spartan card you will have a pose your spartan is in you will be able to chose the pose you like best
What i think would be awesome:
You can change your in game pose. So for example one pose will be while not shooting weapon will be held down when pressure is put on the trigger the weapon will raise, when 4 seconds passes with no fireing reloading melee the weapon will be lowered again.
What do you guys think about this? Wouldnt be cool it would help with machinima too.
