Dead Rising: Case Zero Downloaded Over 300,000 Times

Website GamerBytes is reporting that the downloadable prequel to Dead Rising 2 has now been downloaded over 300,000 times. This means that even if Microsoft is their alleged 30% cut of all profits then Capcom is still pocketing an approx $1.15 million. 

Capcom has sinced announced on their blog that these numbers are not "official" but serve as an early indication of success. Now the question remains is this going to be the gold standard for game demos? Or if Dead Rising 2 underperforms will the blame be placed on the $5 Demo that had just to much to offer?
