If history holds as a pattern, they'll eventually recycle the previous Expeditions. Switch players are currently missing access to rewards from the first 4 expeditions. Recent expedition was decent. I just finished it on Switch this weekend. I didn't bother with any of the sentinel ships. The signal launcher to get a good AI brain didn't seem to work, and I've been reading on reddit that Switch has been having crash issues if you have a sentinel ship in your roster. Btw, you can get both robot helmets if you do a manual restore point before making a choice in the last expedition step, then reload after bringing the construct to life, then on the reload, make the other choice. Your save will remember both options being selected and you can choose both bot helmets in all saves then. Otherwise you'll have to run the entire expedition a second time.
