Delve details on SoA site:

Armor is augmented along upgrade pathways offering customizable (but presumably set) augments.
This has a ridiculous amount of potential just based on the little information there, so I hope they don't screw it up. Note that this is an alliance event, not a party thing.
(This info was posted in dev tracker discussion a little bit ago, but should probably have it's own thread.)
