"Season 1 to Season 2 will happen fairly immediately. We expect S2 to start a week or two after 2.5 hits so we have a date that everyone is aligned on and knows about. S1 will literally end the second we transition to S2.
For example: Season 1 will go to 4:59:59pm Pacific Time and Season 2 will begin at 5:00:00pm Pacific Time."
