Sorry to post again so soon, but I only had time to look at the one image earlier..
Now that I've seen the second image, the one picture in towards the middle of the page looks like it has Cataquacks in it, from Mario Sunshine and Mario Kart DD.
I thought they weren't going to use things from SMS anymore, but here we've seen Cataquacks and Petey Pirahna. I know this is kind of immature, but I am not looking forward to the game that much if those characters are going to be in it.
On a slight upside, though: 3D Dry Bones and Magikoopas! At last!
