Eh, I've seen dozens of articles claiming crazy sales increases in Amazon. It always boils down to a simple mistake - Amazon calculates the increase in sales ranking, not sales, and people misinterpret what Amazon is doing!
For example, imagine an item is in 90th place, and then rises to fifth place. Amazon calculates it as a (90-5)/5 = 1700% rise in sales ranking. It doesn't mean that sales went 1700% up!
Want proof? Here you go:

32,000% Sales Rank in Video Games: 1 (was 321)
(321-1) / 1 = 32000%
Some journalists should go back to school!
"Quite a turn of events occurring within the games industry in the last 24 hours" indeed.
