I think its all but certain it will get a season 2. It would line up time wise for the continuous production schedule they want to get into. DSC will finish season 3 in Jan or Feb I believe. DSC season 3 will likely start airing right away after Picard, So Likey in April. As soon as DSC season 3 ends, they are going into production on Section 31, which would probably be filmed in Sring and Summer of 2020. CBS has pretty much taken over the studio in Toronto, probably to film DSC and section 31, which will have some overlap in filming, with Picard filming in LA.
Probably looking at something like
2020
2-20 Picard
4-20 DSC season 3
7-20 Lower decks
Late 2020 Section 31?
Early 2021 Picard season 2?
Spring 2021 DSC season 4
Then we throw in potential Pike series, and you have the Nickelodeon series, plus a bunch of short treks.
