Deathwatch Cosmetics: Next patch can we got the correct arm?

We've all played the campaign and we know the correct Deathwatch arm is in the game files. As we have more cosmetics for the Deathwatch coming next patch I think it's about time the correct arm from the campaign was put in. Any other arm with some Leadbelcher on it is better than the blank silver arm we've had available since launch. Patch 7.0 is a very fitting time to sort this out as its looked like a modelling error since launch.
