Do you think older games could or will implement Avatar Awards?

I am very interested with the new feature form the update to win awards from games. It really adds a whole new side to achievements and it would be cool to actually SEE something that you have won put on your avatar. Could you imagine being awarded something cool... like The Darkness?? Imagine getting a Darkness award where your avatar has all the snakes and clouds coming from his back... Or winning one of the headbands from the Afro Samurai game! 
 
Do you think this will be implemented into older games or will it only be in newer games from now on? Either way, it's still a really awesome idea. 
 
Also, did anyone else with a Messenger Kit on their controller notice that the text entry box keeps up with your texting better? I've noticed a signinficant upgrade :D

I think MS has stated that this feature will only be in new games unfortunately.
