Galaxy 2 did provide a 10% boost, by M-C figures. That enough to be outside statistical noise.
Trestres there is a big difference between selling 20k / week with 50% price cuts worth 30,000 Yen or whatever it is with a 5m base, and selling 20k / week with a single 20% price cut worth only 5,000 Yen and a base of over 10m. I went on record alot in 2008 / 2009 that it was possible that Wii / PS3 in Japan would end up similar to the DS / PSP back and forth of 2008 in Japan during some future point. Given that DS and PSP are very similar in terms of philosophy, pricing and demographics to Wii and PS3 respectively is it really surprising to see this:
DS / PSP Wii / PS3 DS: PSP Wii: PS3
2004 1394k /476k 2006 957k / 473k 3:1 2:1
2005 4228k/2254k 2007 3674k/1219k 2:1 3:1
2006 8404k/1884k 2008 2893k/894k 9:2 10:3
2007 7209k/3108k 2009 1974k/1767k 9:4 10:9
2008 4017k/3671k 2010 ?? / ?? 10:9
2009 4037k/2302k 11:6
Basically, DS grew from 2004 to 2006 and has declined since. Wii grew from 2006 to 2007 and has declined since. DS had a high peak, while PSP had a low, but late peak - so 2008 was really close. Wii had a high peak, but PS3 had a late peak, so 2009 was really close. Without the PS3 Slim & FFXIII long term boosts this year, Sony needs to be something like 700,000 ahead of its 2009 pace to match it in 2010, or another massive price cut and game push at the end of the year. Nintendo probably doesn't have to be as far up heading into December since the price cut came later in 2009. My hunch is Wii will be right around 2m again, while PS3 will decline to maybe 1.6m and the gap will slowly grow again as it has with DS.
