well i dont know but i am sure it will sell more units than the ps2 in japan.

woohoo! time to celebrate for nintendo by buying a second, different colored version of the ds! :)  actually i dont mind buying another one.  it's like a collectible with a different color.  too bad the US doesn't have navy blue.  i would love that color.

 Now, if it somehow had changeable covers...

Make that 40,000,002!

My girlfriend and I just ordered ours online and they'll be here within days. Only one major problem. We can't play them until our anniversary on the 28th!!! It will be a very painful month!

What a great number of units to be sold in such a short time.

I wonder how the PSP would have done had it been released at the same price? 

"Will DS hit 100m in its lifetime?"

 Thats a big question that has multiple answers. It really just depends on how you phrase the question. Will THIS DS + DSLite hit 100m? Possibly. It'll get close to 90-95, if not more, within the next 2-3 years. The big question is how long nintendo decides to keep the DS.

I know I use the same argument as the Wii, but I just wonder if/when Sony will launch the PSP2 (before a new DS, imo), and if/when Nintendo responds to it.

Provided Nintendo keeps the DS family going...The DS family will easily beat out the Gameboy family (GB, GBC, GBA)'s lifetime sales by a mile, and could get close to rivaling the Playstation family of consoles.

Right now we got:

Playstation Family: 235m units (105m for PS1, 128m for PS2, 5m for PS3)

Gameboy Family: 199m units (via Wikipedia for GB, GBC, GBA, GBASP, GBM)

Nintendo Entertainment System Family: 109m (via wikipedia for NES and SNES)

Double-Screen Family: 40m (DS + DSLite)

Xbox Family: 35m (Xbox + Xbox 360)

The DS family, provided it gets atleast 1 more revision before Nintendo switches to a new system, should pass the Gameboy family. If Nintendo keeps the DS family for 15 years (another 14.5 years), then it should become, by a small margin, the largest family of gaming systems at around 400 million units sold.

I think the DS could use another (more subtle) case shrink in 2008, but I don't see what features of the PSP 2 could threaten it, so we might not see new hardware from Nintendo for a while. Unless they go for expanded media functionality.

I think it could reach the 85-90 millions, but due to production problems is not going to reach the PS2 levels, if they make a DS 2(or advance or whatever) they could reach the the GB levels, the big question is when they are going to release another system?(Sony, Nintnedo and even M$)

The next handheld gen will be quite interesting.

Not 105/128 but 102/115 (end 2006), and don't forget that's is just a shipment figures.

And I don't understand why do you create separate category like "Nintendo Entertainment System Family" or "DS Family"

Because of name?

So N64 and GCN (about 55.5 mln) aren't part of this "Family" (Nintendo home consoles)?

the Nintendo64 should be part of the nintendo home console groups at least.
