A glowing preview from IGN: http://wii.ign.com/articles/115/1154121p1.html
"It has the same addictive, endearing qualities as many of the concepts we've seen come from Shigeru Miyamoto and his team over the past 25 years."
This game is sounding fantastic!
I also added a new gameplay video to the OP, provided by IGN.
EDIT: I also added 5 more previews to the OP, two in Japanese, though.
