Some things from devstream 87 to bump this thread:
-Ambulas remodel/rework, along with a dropship that needs to be destroyed in order to defeat Ambulas
-Sentient Carriers (the same ones from Echoes of the Sentients trailer) that doesn't attack, but deploys a new sentient when they collect those 'sparks' from dead ones
-Defector Rescue (an endless escort mission) that haves you to protect Grineer defectors from infested simply by using life support cells and to direct the defectors to a dropship
-A concept of Nef Anyo is shown of him on a giant control system (and it looks like a Helios sentinel), possibly for either a boss fight and/or a raid
-Sniper Crewman that deploys pads that summon mini Hyenas (the Hyenas are only a placeholder, for that concepts of a ski drone was shown)
-TennoGen
-Baro will arrive/depart 4 hours earlier than he usually would
-Eximus infested will have weakpoints that disable their invulnerability to damage
-The 'Ravenous' Maw is planned as an Operator boss
-Plans for Kingpins for Clans are growing
Also, update title to Quick Steel.
