If you download New Super Luigi U on the Wii U eShop this week, you'll be able to earn double coins (40) for completing the survey for it on Club Nintendo by August 1. Also, if you check a box at the end of the survey, you'll be entered into a contest for a chance to win a Luigi pin.
It might not be much, but at least Nintendo is doing something fun for a new release -- a simple DLC release, I might add! Hopefully somehow Nintendo manages to pack-in the pin for the full retail release, coming in July for the UK, and August for the US.

Final reminder: It's the last day to get your free Wii U game with Mario Kart 8
