You might have brought up a good point. Come to think of it, even Jaune's weapon (it's his family heirloom, but yeah, an important character in RWBY beside our leads, of course) isn't that technologically advanced, technically speaking. So we can't rule out the possibility of having updates over the course of their absence during Volume 1.
