As you probably know, when Geneon USA packed up its bags and departed the New World a few years back, it contracted with Funimation to distribute some of its titles. (Funimation did not become the licensor in this arrangement, just a distributor for Geneon.) That deal
ended in December of last year, and there are now a number of titles that have fallen into licensing limbo. Some of these are well-known and admired shows like
Black Lagoon, Saiunkoku Monogatari, Paradise Kiss, and
Higurashi.
Most of these shows are now generally impossible to purchase in R1. All four titles I listed are no longer available from retailers like RightStuf, nor is there any indication from either Geneon or Funimation that many of them will ever be re-released in R1.
Other series whose R1 licenses have expired or otherwise terminated have been restored to the AS home page,
Sailor Moon being a prominent example. Have you thought about whether the same policy should apply to these now-unavailable Geneon titles?
