XBOXIC has what is still basically a rumour, as it has not been one hundred percent confirmed, it does look like the Dashboard will be getting a big update soon that will fix some of those annoying freezes or other errors, as well as support for a web cam that will come out around the same time. Now you can see who you are going to kill off in game before you do it.
An inside source at Microsoft informed us that Microsoft is currently finishing off one huge update for the Xbox 360 that is going to put an end to all the common problems in both games and the system itself. It will contain fixes for all currently known lockups in games, missing or impossible to get achievements and a bunch of new functionality in the Dashboard.
The update package will be released as soon as possible via a central dashboard update. The webcam accessory is going to be released simultaneously or slightly after, because one of the Dashboard modifications is going to be camera support.
