It's been hinted that the pocket ASLRBs may be available in January, and that they're to include the Hollow Legions updates.
Now as I understand it, the eASLRB is henceforth the basis for all versions of the rulebooks (the notebook ASLRB, the eASLRB, and the pASLRB). If so, then since MMP will be updating the eASLRB in order to print the pASLRBs anyway, I expect MMP might release an updated eASLRB in January too.
Though of course logistical constraints, marketing decisions, Covid, or any number of other reasons might delay it past January.
