Madden NFL 10 for the Wii decided to go a much more cartoonish, "genre defining" route than its PS3/360 cousin in order to "stay true to its core audience." So, if you're looking for a more realistic footballing experience, you won't find it here. But if you're looking some something fine-tuned to the Wii's motion controls and aimed at the more casual player, look no further. And by casual we mean you can apparently tackle someone... without even touching them.
There's a gallery full of new Wii images below, and two videos after the break. You have three more months to get ready for some football, which really seems like a lot of time. Don't strain yourself.
