I'm not sure what the items have to do with the Olympics, but they are: S'mores Pie, Creme Brulee Crunch McFlurry, and Spicy Szechwan and Zesty Mango dipping sauces for Chicken McNuggets.
I guess S'mores Pie (I wonder if the crust is graham cracker?) makes sense as a winter treat that you can enjoy around the fireside and it's not a stretch to say the Creme Brulee Crunch McFlurry (regular soft-serve with bits of caramelized sugar and caramel syrup) is a frosty winter treat but what about the dipping sauces?! (Okay, I did some research... the sauces are "gold" for a "Share the Gold" theme.) I'm surprised they didn't make a special McCafe coffee offering for the promotion.
We probably will be getting the same gold sauces here in the States (Edit: No gold sauces for us! Sweet Chili sauce instead). According to McDonald's Twitter, a top athlete will be dropping by McDonald's restaurants that feature a "How Do You McNugget" sign this Friday. It seems like it might be related. (Update: athletes include Dwight Howard in Dallas, TX and Dustin Byfuglien in Chicago, IL. Check McDonald's Twitter for the latest details.)
I managed to find a review of the S'mores Pie here, a couple pictures of the Creme Brulee McFlurry here and here, but no reviews or (non-promotional) pictures of the new dippings sauces but I would hazard to guess they look and taste like some derivative of McDonald's Sweet and Sour sauce.
