Thanks for the reply, guys! Azrael, the link ( http://www.animenewsnetwork.com/encycloped...ime.php?id=3945 ) you posted answered my question to the tee: "Unlike the TV series, Robotech II: The Sentinels did not re-use animation from another anime other than some flashback footage from Macross; original animation was created for the new series, which was completely inferior to the animation of the Robotech series itself. "
It was nice seeing Hikaru, Misa and Minmay again (looking a bit older even) despite them being not voiced by thier Japanese talents. The quality of the animation was okay to me - it was created by a Japanese studio after all.
