When ORGUSS finished its run in 1984, it was replaced by SUPER DIMENSION CAVALRY SOUTHERN CROSS. Again, there was no relation between the shows other than the words "Super Dimension". 

Two other important events happened in 1984. The first one was the theatrical premiere of MACROSS: DO YOU REMEMBER LOVE? in July. This movie was a condensed re-telling of the original MACROSS plot, with completely new animation. The second event was the release of MEGAZONE 23, one of the first OVA (Original Video Animation, i.e. made-for-video) features ever made. It had the same character designer as MACROSS and ORGUSS, Haruhiko Mikimoto, who had become a fan-favorite due to his previous work in these shows. MEGAZONE 23 PART II was released in 1986. 
 

Carl Macek, a producer for Harmony Gold, came up with an idea which to this day he insists was brilliant, although many purists might disagree. Macek bought the American broadcast rights to SOUTHERN CROSS and MOSPEADA, and rewrote the plots of the three series to get a more-or-less coherent plotline. The "chapters" in this generation-spanning story were now known as "The Macross Saga" (MACROSS), "The Robotech Masters" (SOUTHERN CROSS), and "The New Generation" (MOSPEADA). 

With the addition of a "bridging" episode between "Macross Saga" and "Masters" (created entirely from re-used footage), the episode count was brought up to 85 episodes. And so, ROBOTECH premiered in October 1985 on American airwaves. The rest is animation history. 
 

SENTINELS was to be a brand-new series of 65 episodes, written in the United States and animated in Japan, for North American broadcast. Matchbox, who had the license for ROBOTECH merchandise and was one of the major sponsors for SENTINELS, backed out of the project at the last minute. It has been theorized that low profits on the ROBOTECH toy line were the reason for this. Due to financial problems the series was never completed. All that reamains are storyboards, scripts for all 65 episodes, and completed animation for the first 4 episodes. 

ROBOTECH: THE MOVIE was a re-edited MEGAZONE 23, combined with footage from SOUTHERN CROSS, plus a 12-minute happy ending, comprised of new animation commissioned from Japan. The movie was a disaster: after a few test screenings in Dallas, Texas and a showing at the Los Angeles Animation Celebration, the film's distributor (Cannon Films) decided to cut their losses, and abandoned the project. 
 

While Harmony Gold is still the sole rights holder of ROBOTECH rights to all the ROBOTECH material are licensed to producer Carl Macek, now head of Streamline Pictures, a company formed to bring English-dubbed anime to the U.S. Streamline also sells the ROBOTECH II: THE SENTINELS videotape, as well as the 'Perfect Collection' which pairs two ROBOTECH episodes, and their subtitled Japanese originals on each tape. FHE is still selling the original ROBOTECH episodes (now unedited) in a more conventional format. No firm plans have been made to release either ROBOTECH: THE MOVIE or MEGAZONE 23 in any form, though it is reported that Streamline has acquired MEGAZONE 23 in the last year. The status of the rights to CLASH OF THE BIONOIDS and/or MACROSS: DO YOU REMEMBER LOVE is unclear at this point.
