I think it's telling that the finale for Bad Batch is just a couple days before May the 4th (where a whole slew of things are being announced). I'm expecting the last couple episodes will just get Omega free, see the Empire move Necromancer to Exegol in an epilogue (or somewhere else provocative, and maybe introduce young Gideon as a project lead), and have Omega decide she needs to help get the Force sensitive kids to safety, which will be the subject of a future project.
