What happened to the Brill Josephus series?

There are three major English versions of Josephus: 

• the horrible 18th century translation by Whiston;
• the acceptable 13-volume translation in the Loeb Library series; and
• a projected 12 volume (although at least one of the volumes was split, so now 13 volume) major series launched by Brill to provide heavily annotated volumes of Josephus together with highly new accurate translations.

(Also worth mentioning is Betty Radice’s lively translation of Judean War.)

But the Brill series seems to have been interrupted.  It was originally projected to be completed in four years after the earliest volumes appeared in 1999, and that deadline has clearly been missed.  The last volume to appear in the series showed up five years ago, in 2008 (volume 1B containing book 2 of Judean War). 

It will be a pity if the Brill series is abandoned since it looked to be the best version of Josephus in English; the reviews of the volumes were strong (example 1, example 2).
