You should probably clear your schedule on the afternoon of Saturday, March 5 -- unless, of course, you want to miss out on the coolest* party of the year. On the eve of the launch of Pokémon Black and White, Nintendo's hosting a launch shindig at its Nintendo World Store in New York City's Rockefeller Center. Attendees can check out original Pokémon artwork, and can collect stamps on a "passport," which they can exchange for a limited edition Poké-T-shirt. We're guessing the passport allows you to travel to cooltown**.

Attendees can also go to a special download station to grab a Liberty Pass, a key item which lets players catch the new legendary Pokémon Victini -- which you'll also be able to do from home over the Nintendo Wi-Fi Connection.

* - least cool
** - anywhere but cooltown
