Earlier today, the website for Club Nintendo briefly went live, hinting at products you'll be able to obtain by registering your first-party Nintendo Wii and Nintendo DS games.
A few of the products you'll be able to score on Club Nintendo include Game & Watch Collection for the Nintendo DS at 800 "coins", a DS game carrying case for 600 points, Nintendo Hanafuda cards, Mario Party and Animal Crossing playing cards, a Club Nintendo "hat" game rack, and Wii remote holders.
After only a few minutes, the club.nintendo.com site was pulled in favor of a "coming soon" splash page. According to the site when Club Nintendo goes live you can do the following:
Earn Coins for registering Nintendo products and completing surveys
Redeem Coins for limited edition Rewards
Earn a set amount of Coins each year to gain Gold and Platinum status
Create a Family Account and invite members of your family to join
