Some new stuff which looks pretty interesting, but a lot of it has been around for a while. The exotic materials are definitely new, and there seems to be a bunch of new quest items similar to the wormsinger runes and other stuff we got ttk. The ship stuff also looks cool although obviously that could all just be old stuff that never made it into the finished game which is more likely. The zephocyte and soliton flares were part of the exotic sword quest. Fallen ether is part of the taken war quest on earth and I'm pretty sure swivel turrets and torchlight bindings are from patrol missions already in the game. I think probably the syphon streams, arc inducers and ethereal spines are probably also patrol items for future patrol types, and I imagine the spirit bloom thing is just an error; its clearly just a strange coin. Also think that quite a few of those emblems have been in the game for a while cos there's loads in the armory that I've never actually seen in game with no obvious way to obtain them. The deceptive engram was given to you if you played year 1 and turned into a year 1 exotic, the humble gestures was a reward for some collectors edition or other and the camera has been in the game since beta, just no one knows what its for or whether it will ever actually be available. The theory was it was a way of recording in game footage before the PS4 and Xbox One made it unneccessary.
