FUNimation has discontinued a few of their licensed properties, including the first four volumes of Dragon Ball Z Kai on both Blu-ray and DVD, according to an update posted on RightStuf yesterday.

In an appended update, Crunchyroll News noted that FUNimation confirmed these four volumes were discontinued in favor of “season” sets, with “season two” (covering the third and fourth individual volumes) coming this summer.

The first “season” release for Kai was released back in October covering the first two individual volumes. The set was inexplicably removed from Amazon listings for a short period of time before reappearing, yet still contained the Kenji Yamamoto original broadcast score after repopulating to retailers (despite having Shunsuke Kikuchi listed as the composer on the box art).

The first four individual volumes of Kai (covering the first 52 episodes) were released before the scandal with potential infringement in Kenji Yamamoto’s score broke. After a series of short delays, FUNimation’s fifth individual release of the “refreshed” series picked up with the Shunsuke Kikuchi replacement score.

“Part 4” was heavily delayed by Madman in Australia, and when it was ultimately released, it contained the Shunsuke Kikuchi replacement score.

The entirety of the “refreshed” series has already aired in English on Nicktoons in North America. The seventh volume is scheduled for release this coming March, a full six months after the prior volume last September.
