Phoned to inquire about the 'renegade askari' pack pictured on the wargames foundry site for Darkest Africa, was informed by the chap at the other end(suddenly can't remember his name) who said the pack may be re-released, possibly as either part of a new pack or as purchasable at some future Congo-Themed Event, possibly around March.
He also told me a few tit-bits about the new expansion book, (bear with me if any of this is old news) a campaign system, with troops getting permanently killed/replaced, new scenarios and rules for plenty of new animals including hippos if i not mistaken, and apparently the campaign would span the length (chronologically) of the period (presumably he means exploratory period).
