Darth Vaders arms

Has anyone noticed in the original 2 ROTS trailers, darth vaders arms are up and on the sides (up by his head) when he is raised on the table thingy... But in the new trailers his arms are down by his waist and hips... Why did this change, does anyone know... Is there already a thread on this?

This was already discussed in a previous thread. I will try to find the discussion for you.
