Ubisoft curls up with the DS for a winter sports game [update]

An ESRB rating has been assigned to a mysterious new game called Curling DS. This is either:

• a game based on the bizarre (yet popular!) sport in which players slide a rock down some ice and sweep in front of it
• an exercise game that focuses only on working your arms, or
• a hair styling game.

To be honest, we would be equally amused by any of these! We are guessing, however, that it's going to be the first one. Could this be a localized version of Rocket Company's Minna no DS Curling (pictured)? Ubisoft (the publisher listed in the ESRB rating) has been known to pick up obscure Japanese titles before!

[Update: a news item on Rocket Company's site confirms that Ubisoft has licensed Minna no DS Curling.]
