I read a few articles recently predicting the global down fall of Wii based on current trend in Japan since Japan has always been an excellent market for measuring upcoming trends. While I agree that Wii won't continue its amazing growth rate in the coming year, I don't think there will be a sharp down trend for it either.
PSP has its comeback early last year in Japan with MHP2G and updated hardware. It ousold DS consistently from Feb until early August and almost moved as many unit as DS for the year. While the software support for PSP remain strong and it's still selling well in Japan with MHP2G (although down 40% over the same period from last year), the sale in NA and Others have sunk lower (down about 20% over the same period last year). It's obvious that the momentum PSP had from Japan for sales did not carry over to other markets. However, the announced PSP software lineup outside Japan does improved significantly this year which is a trend we see from Japan.
PS3 has done very very well for Sony in Japan this year. The sale is up 20% over the same period last year and it's consistently outselling Wii for the last two month. However, the sale is down about 17% outside Japan this year. Can we expect the sale for PS3 outside Japan to dramatically improve following the trend in Japan for the rest of the year or next year? Based on the performance by PSP this year, it is definitely not a given. It still might happen but it is certain not a sure thing. The NA and Others markets are not as big game driven as the Japanese market so software alone will not be enough to improve the sales considerablely. While Sony already has a strong lineup of software for PS3 coming this year, it needs to regenerate the interests for PS3 and offer more incentives in order to vastly improve the sales globally.
MikeB predicts that the PS3 will sell about 140 million units by the end of 2016 and triple the amount of 360s in the long run.
