This would be an amazing feature to add.  I'd love to have multiple wish lists (think Amazon level), and be able to set up price alerts.  

An expansion to this would be cross linking this to the marketplace so folks could know if someone is looking for a game (and how much they are willing to "buy it now" for ) would be ideal.  For those that used to love half.com (before ebay decided to trash it), I'm thinking of similar functionality that they had for sellers to find an immediate buyer.  It would definitely make me want to stay as a premium member for these features!
