According to leaks, Season 3 is meant to take place in the early 2410s, almost a 10 year jump from Season 2, but nothing about that trailer seems indicate that.
RMB said 10 years but Terry mentioned on Twitter a while back it’s about a year between seasons. I guess I’d go with the showrunner’s answer, but it’s weird that the RMB leak seems so spot on in a lot of plot points yet some of the details are off. Makes you wonder exactly what it was he saw.
