If you're nearby New York City and have Layton fever set aside some time on February 10th (i.e. this Sunday). Nintendo is throwing an event to celebrate the release of Professor Layton and the Curious Village and the debut of the Cobalt/Black DS Lite at the Nintendo World Store. From 1-3PM event goers can purchase Layton a day early and compete in live puzzle challenges to win prizes. One of them will be a Cobalt/Black DS Lite, which will also be sold a day early just in case you don't win it.
Siliconera has the details, schedule and venue of the launch party.
