Nintendo shares dropped more than 2% in Tokyo overnight after it revealed profits had dropped by 55% in the three months to June.
With no information imparted regarding a successor to the Switch, Nintendo said sales had fallen in both its game software and machines divisions.
The Switch console has been on the market for eight years now, with the Japenese video game developer having sold around 140 million in that time.
However, attention is now turning to the next generation, with Nintendo's president Shuntaro Furukawa having promised an announcement would be made on the new console by April 2025.
Profits for the Super Mario maker reached 81 billion yen (£427 million) for the quarter, marking a 181 bilion yen drop compared to 2023.
Quarterly sales dropped by over 45% to 246.6 billion yen for the period.
