According to August Ragone, Mill Creek is planning to release an usual hodge-podge of animated features, animated T.V. shows and Honda sc-fis, in a two-disk set come February 5th, 2019. The most significant of this package is Toei's "The Little Prince and the Eight-Headed Dragon", which tells the story of Prince Susano-o as he does battle with Orochi, the eight-headed dragon (and later to be the inspiration for Ghidrah). The other titles include two of Honda's Columbia Pictures releases ("Battle in Outer Space" & "Mothra"), as well episodes of Astro-Boy and Godzilla (1998) animated series.
I know that "Battle in Outer Space" is already available in blu-ray form, as well as the "Icons of Sci-fi: Toho Collection", so this would probably be double or triple-dipping for some. For myself, because it does include "The Little Prince" complete with a rousing score by Akira Ifukube (I believe it was his only animated feature that he worked on), I think it is worth the dip.
