Our papa-site Gear Live pointed out this video from MyGamerCard.net that was supposedly leaked from Gamespot.com. This one is looking real legit, and boasts some exciting features:

 
* Ability to add up to 600 Windows Live Messenger contacts to your Friends List.
* Text chat with up to 6 Live Messenger contacts at once during games or movies.
* The Marketplace will be getting its own Dashboard Blade.
* The Marketplace will be skinned independently of the Dashboard, for special events.
* The Marketplace will be getting a new, easier-to-navigate remake.
* Achievement Pop-ups will now display how many points and which Achievement you have gained.
* Low-power downloading (fans off) and auto-off after finishing queued downloads.
* View partially downloaded video files.

Much like Gear Live, we’re still wondering “where the browser at?”, but it’s looking like Microsoft is still doing a great job of beefing up their already impressive online features.
