Wii is going through the usual ups and downs of different times of the year like every other consoles now... outside of Japan of course. Remember throughout 2007 and 2008, Wii was sold out. Sales on a weekly basis were determined more so by weekly shipments rather than if it was a slow month in the summer. So like other consoles right now, they are not doing as hot as they were doing in January and subsequently in October onwards. Or at the end of fiscal quarters such as March, June, and September.
However, Wii is down a little more than usual from the possibility of no dominant software especially from that of Nintendo in the early parts of the year. Last year, it had Super Smash Bros Brawl, Mario Kart Wii, and Wii Fit all release before the end of the first semester. This gave Wii an extraordinaryly unnatural amount of sales in the first half which is unusual for any console. However, in the first half of 2009, the dominant software has been niche exclusives from 3rd parties such as MadWorld and SimAnimals with Nintendo's main showing being remakes of old Gamecube games.
This lull in big properties in the beginning of the year also contribute to Wii's apparent lull in sales compared to 2008. However with Excitebots just releasing and Punch Out on the way we can assume that Wii will start to do a little better as it gets dominant software. Even more so when Wii Sports Resort comes out. Then of course with better 3rd party outings such as Little King's Story, Boom Blox Party Bash, Grand Slam Tennis, Tiger Woods 10, Virtua Tennis 09, etc start to come out as well you'll see sales continue to stay on the normal trail of things for a dominant brand console.
Japan, on the other hand, has no sign of a desirable future but it could possibly be going through something similar tied in with a much more apparent economic constraint on the video game market. But titles such as Monster Hunter 3, Wii Sports Resort, Punch Out, etc should all help to alleviate the problem in the future.
So most of it is Wii no longer being sold out so we have to adjust to different sales trends but some is due to no dominant software in the first few months of 2009 compared to the first few months in 2008.
