Charles Martinet, the man who provides the voice of Mario, has said a new instalment in the series is on the way.
That's if a Twitter page purporting to belong to him is genuine - it looks authentic, anyway.
"Mama Mia!!!! I'm going to Seattle this week to record a new Mario game!" Martinet wrote on 10th October. Then, two days later: "Big day tomorrow! Seattle for a new Mario game! Yippee!!!"
But the most interesting message appeared over the weekend. "Awesome new Mario Game!" it reads. "And it's not NSMB Wii, and it's not Galaxy 2, but it's going to be crazy fun!"
Mama mia indeed. Nintendo has yet to comment on Martinet's message.
