Nintendo never confirmed that they are selling the 3DS with lost. It is only a rumour and very unlikely.

Guys, this month 3DS did good.
It's true, the number of units sold per week has decreased from 58k to 52k, and I thought it would have done at least 300k, but this can happen after the first week with the cut in effect, especially if it has no games able to carry the hardware (even if SF did 130k very good especially seeing the install base).
But the most important thing is that 3DS is eating a lot in DS sales: this month DS did only 145k, with a decrease of weekly sales from 41k to 29k of average.
This means that audience is shifting with a good pace from a console to the other.
And, above all, even if no one remembers it, in USA the adoption of a new console is far far slower than in Japan.
360 had a very slow start.
PS3...we know, but in that case the absurd price is the real reason.
Wii had a good start, and a good first Holiday, but records started being done in its second year (also because in its first year it suffered severe shortages, but also the second year it had them )
DS...eeeh...DS NEVER did over 200k in its first 20 months (except for Holiday months, obviously), and it was doing bas number, behind GBA. It suffered a LOT GBA, Then, the Lite and NSMB came, and the rest is history.
So, the fact that 3DS is already eating lots of sales that, without a price cut, would have been directed to DS ( remember that DS obtained to do almost 400k this June... it was still a monster! ) is VERY good for the future, especially with the two Mario games incoming.

For a console that hasn`t got a system seller so far and its game library is small and not yet showing the strengths of the console, i think 3DS is doing pretty good so far.
After Mario Kart 7 comes out, i think average sales will increase (for next year too) seeing as Mario Kart series has become a force with casual gamers.
Of course, holidays and more games like Mario 3DLand, RE Revelations and MH3G will help 3DS this year and the next.

It is definitely not doing great and most likely is overtracked in EMEAA, as well. And while it is still doing very well in Japan, we need to wait til Sony launches the Vita to see how it will affect sales.

But still, it's way to early to call it a failure. As above, we need to see what affect the Vita's launch has on the 3DS's sales in Japan. And when it can truly be predicted is late holiday next year, when we see what kind of impact the Vita has on it WW.

It should do wit hthe software coming and the seasanol boost.

IT'll be doomed depending on games coming and in the future of it's library

Ground on the competition.

For fans to brag whos the winner and whos the loser. For corporations to get a bigger market share.

But for us, especially since Sony is making the worst decision imaginable (not releasing in NA/Europe this holiday), the install base will look pretty big after the holidays compared to the Vita. 

Its just economics. You commit handheld games to the guy with the bigger install base. 

If this gen has taught us anything, it should be that consoles can gain a lot of steam later on, a slow start might not mean anything at all.
Then again, I'm unsure of the future of handheld gaming and the role tablets and smartphones will have in it so this is hard to say.
But, no matter what happens, the 3DS is more than likely not "doomed" or "d0med" or anything of the sort. The only thing I can say for certain right now is that it is extremely unlikely to come anywhere near the DS' sales in its lifetime.

Since when selling at the same pace as the best selling console of all time is considered doomed?
