A preorder card for Super Smash Bros. for Wii U that surfaced online suggests that the game will release on November 21, 2014.

The card, a picture of which was posted online by Twitter user BluesDriveBuster, seems to have come from the American retail chain Fred Meyer, and looks authentic. The release date it lists also falls into Nintendo's official release window of winter 2014. Of course, the retailer could just have listed the wrong date by mistake, and we won't know for sure until Nintendo makes an official announcement.

If the release date is accurate, Super Smash Bros. for Wii U will release a full month after the release of the 3DS version, which comes out October 3.

Yesterday, our time with Super Smash Bros. for 3DS also revealed that you'll be able to use Nintendo's handheld to connect to the Wii U and use it as a controller while playing the console version of the game.

If you want to check out more Super Smash Bros. for 3DS, we spent an hour playing through the game yesterday. You can watch our playthrough below, or check out a montage of the main characters' Final Smash moves. We'll have a lot more videos, and full rundowns on the game's unlockable characters next week.
