As reported on Gamespot, Funimation announced during Otakon 2018 that they'll be releasing the entire Tales of the Abyss anime series as a complete set for Blu-Ray, DVD & Digital Download on November 27th, 2018.
This isn't the first time that the Tales of the Abyss anime was officially released outside of Japan, as Bandai Entertainment released the show first in 2011. The company became defunct in 2013, and several other companies picked up shows that they licensed, including Funimation. One of the shows that they picked up right away was Tales of the Abyss that year. Just like the Bandai Entertainment release, Funimation's release will also be Japanese audio only with English subtitles.
Special thanks to @werifes for the heads up.
