Apparently, it was re-released in movie format and so far 2 have been fansubbed with new music and it looks like even new animated sequences.
They actually got a majority of the original voice actors on board, I'm just floored that after 20 years they where able to do that. JOY!

All I can say is wow. It gave me shivers to watch this, I recommend to other Gundam fans to check it out ASAP.

Anime News Network wrote:Plot Summary: 87 years since the day when mankind first immigrated into space colony along the orbit of Earth, militarism had etched into the corrupting Federal government, once victorious in the One-year War, 7 years ago. In response to this situation, an initially anti-earth collision, A.E.U.G., started its moves. Chaos might be raveled again, and disturb the pseudo-peace of populated solar system, destroy youths and their romance. Heroes and the wise who experienced the One-year War might survive and fight with, or against each other's might, once again. A remake of the original 50-episodes "Zeta Gundam" series, this trilogy features adjustment to character designs and up-to-date new scenes.

Comment:
Digitally remastered compilation movie trilogy for the Zeta Gundam TV series with some new footage. Made for Zeta Gundam's 20th Anniversary celebration.
Like the Mobile Suit Gundam movie trilogy, the majority of the original cast of Mobile Suit Zeta Gundam reprised their roles for this theatrical version - with the exception of Yukana replacing Saeko Shimazu as Four Murasame, Satomi Arai replacing Miyuki Matsuoka as Fa Yuiry, and a few others.
