Sony is, and hopefully they'll do something with them. I've been waiting for an announcement but so far, nadda.
As for the Miniseries, those were quite a bit a part. The first two mini series aren't a part of season 1. Season 1 began with the Pyramid of Darkness Miniseries which was included on the Season 1 part 1 set.
edit: and worth mentioning, the miniseries DVD set came with
this snake-eyes figure.
