Well they didn't mention that in detail yet, no? Mind you, all I've heard so far was that they're implementing a lot of new camera controls/options/interface improvements, but they have been awfully secretive on what exactly they've done (except camera controls, there was a post on that from the devs in their forums).
One negative thing though - "battle generator"?! Again?
I am seriously hoping that they're not going to leave it random as in DG. Being able to select fleets for a quick battle is just really essential, ESPECIALLY for multiplayer. Keeping my fingers crossed that they change that.
