Super Mario X was added to Nintendo.com's game index yesterday. Without a doubt this is a very interesting development.

Checking to see if the game would still be at Nintendo's site I noticed today that they have removed the game from the index. However, they neglected to remove the Audio/Video page of this mystery game. See here:

Nintendo.com has made some few mistakes in the past... could this be one of them? Or are they trying to cover up an info leak?

We will keep you updated!
