I think Call of Duty: World at War will unfortunately be a failure, simply because of Treyarch's murder of Call of Duty 3. If they are lucky this one will redeem them, and counting on Call of Duty 4's success they may get lucky, but no one will know until some better videos or demos
Although i do recon on the question, that Microsoft's announcements were pretty cool, the new dashboard looks nice, ive got the video of it on my HDD
Going to be nice, i like new things like that.
