It’s not exactly the major coup Sony needs to become a gaming leader once again, but surpassing Nintendo Wii console sales in a market like Japan — even for one month — is a pretty big deal. Fueled by new game titles such as Resident Evil 5 and the PS3 exclusive Yakuza 3, Sony managed to outsell the dominant Wii box by nearly 50 percent in March. No, seriously! According to Enterbrain, a Japanese game magazine publisher, Sony sold 146,948 PS3 consoles in March while Nintendo managed to hawk a mere 99,335 Wii units. For comparison sake, Microsoft shuffled out 43,172 Xbox 360 consoles. No, the Earth isn’t exactly reversing on its axis just yet. While we applaud Sony for a solid month and for topping Wii sales in Japan for the first time in nearly a year and a half, big exclusives aren’t going to be coming around every month to help push units out the door. In order to right this ship, at least where gaming is concerned, the company still needs to find a way to bolster sustained sales growth — surges aren’t going to help in the long run.
