On February 1st, the Sword Art Online – Sing All Overtures concert was held at the Pacifico Yokohama National Convention Hall in Japan and with this came hope that a third anime adaptation of Reki Kawahara’s Sword Art Online would be announced.
Sadly, the event came and went without any official mentions of a third season or any other plans. What did come after the event was the confusion and hoaxes afterwards due to this image:
This image is from when Bandai Namco announced the Sword Art Online: Lost Song for the PlayStation 3 and PlayStation Vita, the third game in the series based on Reki Kawahara’s Sword Art Online at the Tokyo Game Show stage event last year.
Reki Kawahara’s Sword Art Online light novels are still ongoing and have another virtual world, UnderWorld, and a fourth major Alicization Arc that kicks off in volume 9 and is still running in last August’s volume 15.
