In a brief message on social media at the start of this month, Kirkhope mentioned how he thought his time writing music for Mario was "at an end" after 8 years, signing off by saying he was "going to miss" Nintendo's famous mascot:
This news follows Ubisoft teasing the second Sparks of Hope DLC 'The Last Spark Hunter' at the end of May. There's also a third DLC coming later this year. It will feature Ubisoft's iconic character Rayman. Apart from the Mario + Rabbids sequel, Kirkhope has also worked on the original Mario + Rabbids game and has composed music for the Banjo-Kazooie fighter update in Super Smash Bros. Ultimate.
Mario + Rabbids' future beyond Sparks of Hope is currently unknown, but at the start of this year, Ubisoft said it was "disappointed" with the sales of the new entry and a few other titles like Just Dance 2023, despite "excellent ratings" and ambitious marketing.
