The OFLC has rated a Nintendo published title called Rock n' Roll Climber, and Siliconera has begun to speculate that it may be a sequel to the classic NES title, Ice Climber. As pointed out, Vitei, the game's developer, previously worked on 1080 Snowboarding and a Japanese-only puzzle title, Theta.
While I have fond memories of the original (and that damned bird that used to steal my vegetables), and I'm not ruling out the chances of a sequel, what could Rock n' Roll Climber actually be? I mean, Ice Climber made sense since you climbed, you know, ice.
But Rock n' Roll Climber is open to interpretation. It could be a game about climbing rocks, sure, but what about the "roll" portion of the title? The only thing I could think of is that Nintendo is getting in on the popularity of music games and has Vitei working on a title about groupies. Where you actually physically work your way up the rock n' roll food chain. It would be like Rock of Love, but with 100% more wooden mallets.
