I wish they did a platform breakdown by model. I want to see how close PSP go is to it's first shipment (150k).

No where near a bigger difference than what has happened with PS3 and Wii. 2007 numbers following...

Wii - 3,677,579
PSP - 3,061,395
PS3 - 1,218,612

2008...

PSP - 3,639,073
Wii - 2,888,251
PS3 - 1,000,838

2009...

PSP - 2,282,912
Wii - 1,987,526
PS3 - 1,795,568

I think 2010 could see PS3 > Wii in Japan.

PS3 best year vs. Wii worst year = Wii > PS3 by a sizeable margin.

This is why I don't share your prediction. I think PS3 peaked this year.

Isn't it alarming that the Wii had its worst year though, despite the biggest console game this gen (NSMB Wii). Monster Hunter 3, Black Wii, Pricecut, Tales of Graces, Wii Sports Resort/ Wii Fit Plus? I think the downward trend of Wii will continue, although it wont be too much lower. Of course though, if DQX releases... Plenty of crow coming my way.

Then though, what does Wii have confirmed in 2010?... I can name a whole bunch of moderately big games on PS3 in Q1/Q2 alone. Would like to know the Wii lineup if someone can help?

lol Wii is going down year by year in japan

good for wii, I hope it hits 10mil before ps3 5mil

Wasn't it at about ~64K up until the previous week? If you figure it's at about the same numbers that MC put it at this week(4.2k) then it will probably be about 68k or 69k sales thus far.

Well, the reason for that is the massive decline in the first half.  2nd half (ie: when all those factors you just listed actually came into play) Wii had a a generally flat or better performance than 2007 or 2008. 

And despite dropping massively, Wii's been narrowing the difference between it and PSP.  Last year they were nearly 800k apart, this year that's down to 300k.  Pretty notable, if Wii continues it's 2nd half turnaround and PSP continues it's general decline (which was consistent YOY bar a brief relief from the pricedrop), we'll see Wii overtake it for 2nd place next year.

As for future lineups, likely 500k+ sellers (or close to it) currently announced for all 3...

PlayStation 3

• Gran Turismo 5 (March 2010)
• Yakuza 4 (March 2010)
• Metal Gear Rising (tba)
• Final Fantasy Versus XIII (tba)

Wii

• Super Mario Galaxy 2 (2010)
• The Legend of Zelda (2010)
• Wii Relax (tba)
• Dragon Quest X (tba)

PSP

• Kingdom Hearts: Birth by Sleep (Jan 2010)
• Metal Gear Solid: Peace Walker (March 2010)
• Monster Hunter: Felyne Village (2010) 
• Agito Final Fantasy XIII (tba)

Yeah, it's pretty hilarious.

You're kind of eschewing the facts there.

NSMBW came out to incredible sustained sales and has given the Wii both its best selling ever, and the best selling week ever of any home console. The Wii is also up YoY in the month of December. Considering the sheer magnitude of 2008's sales for the Wii, I think this is a highly significant indicator that the Wii is doing strong (especially considering that pundits predicted this would be the worst Christmas for the Wii).

I'll leave list wars for other people to take up.
