Gundam character illustrator and anime director Yoshikazu Yasuhiko stated in his recent interview with the Daily Sports newspaper on August 13, 2017 that he is open to the idea of remaking the original Mobile Suit Gundam 0079 anime series.
He got asked if they would be willing to continue the prequel Mobile Suit Gundam: The Origin anime series to its sequel One-Year War series. Yasuhiko replied that he'd be lying if he said he wouldn't do it. Though the length of the story is no joke! and the staff feels the same way about it.
Daily Sports also reported that there is a "big project" or projects on going to commemorate the Mobile Suit Gundam's 40th anniversary in 2019, but did not clarify if the project is going to be the remake of the 0079 series.
