The Mario posters will feature original artwork. Both of the other items are already available for users in Japan. Game & Watch Collection 2 is the sequel to one of the first Club Nintendo rewards, which has since sold out. Grill Off! is based off of one of Nintendo's old toys, the Ultra Hand.
What are you talking about? A DS game and a WiiWare game, pretty good.
Even in Japan though, the soundtracks are the end of year bonus and not part of the average Reward Catalog (for example, the Super Mario Galaxy soundtrack was one of the end of year bonus choices for those that reached Platinum status in 2007). Nintendo announces some pretty cool things and you still complain. Do I wish they would offer something like that baby blue Wii Remote? Yes, but these are some pretty good rewards.
So, it is completely fair to criticize the rewards being offered, especially when we can compare to the Japanese and even European (Stars for Wii Points) services.
