Forum:Wall Chests in the Armory

I cannot find a clear cut answer on this topic. I have watched recent videos on youtube that show the chests in the wall section of the armory to be above lvl 48 the user is using the pc version of borderlands tho. So basically I am wondering if I move onto the last quest "Its Like Christmas" do the wall chests advance or stay lvl 48? (i know about the 2 lance chest rooms)
