Coming in August: ThunderCATS: Season 1, Volume 1
Coming in July: The Best of He-Man and the Masters of the Universe
According to this, a classic cartoon special from the 80's will see the light of day: He-Man/She-Ra Christmas Special. ( another review of it here )
Already out and I didn't even know: M.A.S.K ( Hell, even C.O.P.S is out on DVD )
Now all that is left to come out is Silverhawks! I've yet to meet anyone who remembers Beverly Hills Teens which came out way before 90210.
