Honestly, I don't like the new WoK belt at all. The belt is too thin and the buckle (specifically the circle surrounding the delta) looks very flimsy and does not match canon. I'm holding out for a bit in hopes that they fix it before I redo the guides.
And I've been busy trying to level my Klingons recently (whose pallet has not changed), but I'll check out the new color pallets and see if an update is necessary.
i agree that the belts don't match too well, the medallion of the buckle is way too small and needs to be re-sized.
The rank pips on the shoulder and sleeves still aren't fixed in so that you can set them to differing proper ranks yet. if they need reference material i know of several places to find the actual graphics used in the films.
