Wizards of the Coast Sues Rumor Site

This suit has come as a disappointing and disturbing shock to Magic's large and diverse community and raises several questions too familiar to Slashdot readers: Do leaks of upcoming products really hurt sales of those products? Do these kind of lawsuits damage the companies initiating them more than they help?"
