User blog comment:Crimson Storm Mich/Future Units Preview v2/@comment-28139161-20160828151205/@comment-27691408-20160828172612

The next batch being created is about Karl's past, Zellha and quaid follow the same path as avant, Sirius, and Mifune. Meaning their current lore revolves around themself or pre-existing units so a "life of batch" is very unlikely especially for quaid because we already know most of his life and Zellha fits into the  Bariura section of units which qualifies her to be a 1 and done unit.

On the bright side Karl's past batch with 6 units.
