There's no Club Nintendo insert and it's not printed on the back of the cover. The game is still listed on the eligible product list... I made sure about that before I bought it because I only need 35 more coins to reach Platinum. I bought the game for that specific reason.
I've emailed Nintendo about it already earlier today, but I'm worried about not getting a response. I emailed them about something else last Friday and never got a response other than the email confirming they had recieved my question.
