I believe that BioWare will find a way to re-implement the system, because I believe them at their word. We will just have to wait to see when that will be, because as they said in this post (http://www.swtor.com/blog/why-unify-color-chest-piece-gone-and-whats-next), and based on your responses, it was a very popular feature.
But for those of you who think we can get by without a matching color system, by just playing more to get the full armor set, you aren't realizing that some armor sets are not complete.
For example: Boarding Party and The Foundry drop Orange Head, Chest, and Glove pieces. While there is a set of BH specific greaves, they are blue. So the armor set for those two flashpoints is incomplete.
Hell, I keep my T1-5A Imperial Security Body Armor, the BH chestpiece from The Foundry, on Torian because his default pants, black with a bright yellow line running down the side, match the white and bright yellow chestpiece better than anything I can find for my character.
I'm excited to see BioWare's future implementation of a new Color Match system, I just hope it happens sooner rather than later.
