I just recently renewed my subscription to Nintendo Power for the sweet, sweet gift. This time, I am getting the Twilight Princess 'Official' Player's Guide (Both versions, I presume).
So, I bet you all want to subscribe to Nintendo Power now, right? Well, here's the thing. Apparently, I am not only getting a Player's Guide for Twilight Princess, I am also getting the soundtrack CD for the game. That's where the "rumor" portion of the title of his update comes into play.
TSA called Nintendo Power and they said they couldn't verify whether or not I am getting a soundtrack CD or not. But, it definately shows up in their system. Here's a screen capture:

No one is sure about this, yet. So, The Hylia will be staying on top of it for everyone else! Stay tuned!
Edit by TSA: It's like the same thing that GameStop told me when TP went out of the system, but still showed up. The promotion code has the information about a "CD" with the subscription offer, but in their actual product inventory, there is nothing about a Twilight Princess CD. This is more than likely TRUE, it's just somebody jumped the gun with the promotional code description (or else to avoid confusion, they just put all the info in it now).
