Yes it is. I own one. It is the new wii and it is really fun. You have a big main controller and the Wii is built into it and you need the old controllers to play some games. The Black one is more expensive but has more memory than the White one.
My cousin brought his over for Thanksgiving and it is really fun. You can create your Mii by taking a picture of your face with it and sometimes it turns out freaking hilarious. I really wish I had one. :(
