Red 5's dev round table on Twitch earlier today? I didn't either, but fortunately the Firefall Twitter account susses out several of the more interesting tidbits.
The team mentioned the MMO shooter's revamped progression curve, which has changed to the point that "you will feel the difference." In-game mailboxes, separate chat channels, "rare legendary weapon drops," and clicking-on-player-names-to-whisper are just a few of the features in the works. The game's HUD is now drag-and-droppable, and the crafting UI has a new and less confusing layout.
There's more where that came from, too, so click through the links below to read all about it.
[Update: The official site has updated with a dev blog outlining the Q&A!]
