Rumor: Microsoft Is Thinking About Digital Game Trade-in For 10%

Recently, a NeoGAF user claims that Microsoft perhaps is thinking about digital games trade-in for Xbox games. This user said that he saw a survey about selling back games on Reddit. According to the screenshot, the survey is posted on Reddit and each game is selling back for 10% of the purchase price, however, there is no any confirmation from Microsoft about this survey. 

Whatever, if this survey is true, if the console digital games store offer you the option to sell back game to Microsoft for 10% of the purchase price, would you sell back your digital games? Or, you may think this price is low or high? Let us know in the comments if you have any suggestion.
