It's been a long development cycle for Super Smash Bros. Ultimate with the team not only celebrating the initial launch of the game but also multiple updates and DLC fighters over the past five years.
Now that the Sora (Kingdom Hearts) amiibo has arrived, the game's director Masahiro Sakurai has taken to social media to thank the team for their hard work on this latest release, and acknowledge the fact this is technically the end of work on Ultimate. It's finally done!
Here's a translation, courtesy of DeepL:
Masahiro Sakurai: Sora's amiibo is available today! Thank you so much to everyone involved (I think it's awesome). The original perfect design, and the coloring is precise and perfect. The modeling and poses are good.
Now that all the fighters have been converted into amiibo, the work on "Smash Bros SP" has finally come to an end.
Although Smash Bros. is winding down, recently it's received new spirits and events celebrating the game's fifth anniversary. The Sora amiibo is also available now and yesterday the game was updated to Version 13.0.2 adding support for this amiibo.
