World-Wide Revolution Launch Unneeded
GamesIndustry.biz reports that, in the words of Nintendo President Iwata, a simultaneous global launch for the Nintendo Revolution is not necessary. From the article: "We don't think it's necessary to do the simultaneous worldwide launch simply because others are doing this." He also goes on to mention that they plan to have the DS shortage problem at least partially taken care of by the end of April.
Worldwide launches are OK if you know you have enough units to make everyone happy, otherwise they aren't. Look at xbox 360. Tons of units sitting on the shelves in Japan, and people can't even find one in the US. Customers get very annoyed when they can't get something that's been released. Retailers get mad when customers leave their store empty handed because they don't have access to the products that the customers want.
