In an interview in the May issue of Enterbrain's Otona Fami magazine on Friday, director Yoshiyuki Tomino revealed "for the first time" that he has plans for directing a new Ideon work. The topic came up after the interviewer discussed the restructuring that Tomino did when he turned the original 1980-1981 Densetsu Kyojin Ideon television anime series into The Ideon: A Contact (1982) and The Ideon: Be Invoked (1982). He mentioned the new Ideon plans when discussing how modern audiences would react to the starkly depicted death scenes in Ideon.
According to this (Link), it seems there is a chance we get to see a new Ideon animation. If you ask me, I hope it's not a sequel. Well, it's not quite possible anyway. I guess it will turn out to be a remake of some sort. Since many old-school Super Robot shows get remaked this recent years. Anyway, hope you look forward to this, and stay tune.
