Rumour: Super Smash Bros. for Wii U on November 21?

Nintendo has still not communicated a certain date on when the upcoming Wii U-version of Super Smash Bros will be released but someone found this discount-card for Black Friday on Twitter and it seems like the game will hit stores the November 21. Black Friday is the 28th which would mean that Nintendo will not miss out on the biggest yearly shopping day in the US and it is basically a must to release your game ahead of this date if you want a major part of the holiday sales. Naturally this could be a fake, so don't circle the date in your calendars just yet.
