Electronic Arts and other video game publishers were sure that Sony's PlayStation 3 would be the hot console right about now. They generally underestimated the success of Nintendo's Wii, which has become the top-selling game system this year.

According to Bloomberg, Electronic Arts experienced a 25 percent drop in sales in February from a year earlier because it didn't have enough Wii games. Now, the company is rushing to get out Wii games as fast as it can.

Research firm IDC is estimating that Nintendo will ship 16.1 million Wiis this year, according to the article, compared with 9.9 million Xbox 360s and 9.1 million PlayStation 3 systems.
