With Lind's banner ending just before the anniversary, the next events will most likely be the UMPs bizarre's adventures (featuring RO) which should take 2/3 months to complete, just enough time for a new major event, and so it's likely they will be followed by DEFY's return
I would be very surprised if the banner order will differ. Lenna (a first half-year doll in CN) has been delayed beyond the first year at this point so they really can't delay her any further. Also with Lind technically we already got all the "filler" dolls between Deep Oblivion and Corposant so unless they throw global a curveball then we should not expect any of the recent CN dolls to appear before march at least. The only exception would be if they pull another triple unrelated event banner like they did with Andoris, Belka and Jiangyu, but this can only work with Lenna and Laine. since Lewis, Helen and Phaetusa don't have a big enough connection to pull that off
