Smash Prodigy Shown to be a Possible Fake

Smash 4 (Wii U) is coming out soon on November 21st and the hype has been insane for this game.  Events are being held and tournaments planned.  Yet out of all of this an interesting occurrence arose of a 10 year old girl named Karissa who is now being called by some "Karissa the Destroyer" for her amazing Smash 4 gameplay ability. 

And now she is being shown to be possibly a fake set up by Gamestop. 

I was amazed at what I saw when the article first got my attention and I saw the immediate reactions where people claimed it could not be true.  I honestly hoped that it wasn't and even mentioned the people who claimed my own experiences with gaming have been Nintendo "plants" for publicity.  I even went so far as to comment about it stating as much. The video looks real (as seen below) but there are some pretty big bits of evidence that have come up showing this to be a Gamestop fake.

People on Reddit have been looking for proof one way or the other in regards to Karissa and have come up with some pretty solid proof that she is an actress hired to work this event.  Below is a casting call that was placed by Gamestop for basically the exact situation that occurred.

The final nail in this coffin seems to be Karissa's apparent other commercials that have started to pop up.  you would think that in this day and age companies would realize that the internet will find things like this pretty quickly after they come out if there is a setup.  So what do you think of this whole situation?  Do you agree that if this was a humorous set up or a commercial it would be better instead of a ruse? Let us know below in the comments, on Facebook, or on Twitter.
