I need someone to state what the core/casual difference is here before I comment.
I will say the sales aren't a surprise. Based on sales of titles on Kinect so far the breadth of genres it can support well seems pretty narrow so far.
You could blame the games, but to be honest, a a tri-console owner I think that fact needs to be faced that Kinect on it's own only really supports certain experiences well vs say the Wii or Move. The lack of Haptic feedback and focus on body motion vs simulated inputs (press a button to fire something for example) seriously reduces it's capabilities.
We'll see how Gunstringer fares, but I'm expecting just above Eden like sales for that. Given the first reviews make clear it's short and it sounds like a down-loadable title pushed to retail (like Eden) I don't expect it to sell bucketloads in the current climate.
The holiday season will be the real test though for Rise and stuff like Gunstringer. If they see a pickup then MS will at least know that titles like that must release around buying spikes, if not then I think the jury will be more or less in on such titles on Kinect in the near future.
Try to be reasonable... its easier than you think...
