According to GamerBytes, leaderboard data shows that Dead Rising 2: Case Zero was downloaded over 300,000 times (328,290 at the time of writing). Even with Microsoft's alleged 30 percent cut, one can estimate that Capcom made roughly $1.15 million off the experiment in less than a week.

Publisher Capcom insisted on its blog that "these are NOT official numbers," though we think they serve as a good, early indication of success. Two interesting things are at play here: Will the Case Zero experiment usher in a new type of demo experience? And if sales for Dead Rising 2 fall below expectations, will Capcom place the blame on a $5 demo that proved a little too satisfying?
