I well and truly believe that it ias time for the dwarves to get new armour...at least the gaurdians,the rest can stay the same,it dosn't have to be movie design but perhaps their own interpretation with movie insperation
If you look at the thread about a new possible film-based design for the Dwarves in the Dwarven Section, you will see that a lot has been said about possible proposals and compromises.
But, in the end, the final answer was very clear: the Edain Team has currently no interest in modifying all its 'graphical system' of the Dwarves, as it would involve a necessary general modification, and, most importantly, the majority of the people of MU has expressed its disaffection towards the Hobbit trilogy's design.
So, for now, there won't be any significant change about this matter
