February's npd will have one week without new 3ds/xl existence,so I'm seeing 15-20k for that week,for the rest of the three weeks with the release of new 3ds/xl and the releases of Zelda:MM 3D and monster hunter 4(maybe there are more releases that Ι might be forgetting but these two are they main games),the fact that dsi sold 500k in the first week of release in the USA,the news that New 3ds xl is selling out,and not only the limited editions(I'm pointing this out as many you could say that limited editions are expected selling out because of the low supply),the basic New 3ds xls too!New 3ds/xl come after two years and a half from the 3ds xl version release,so a singificant time has passed since that,that's an advantage...
The exclusive games that it will get,for example xenoblade x on wii ,had a decent perfomance in the USA!
Lastly,of course the radical redesign,the many enhancements and additions it has(Better cpu,better screen,better speakers,better cameras,better internet browsing,html 5 so youtube compatability,etc) and the 3D effect that is now completely usable,it's simply the 3DS that we should have from the beginning!It's a worthy upgrade and 3DS has still a plenty room for further growth in the USA!
Also,there is considerable anticipation for this system,it was obvious since its announcement in Japan,since that its sales decline even more!
I m estimating,15k-20k for the 1st week without New3ds/xl,230k-250k for the 2nd week with its release,120-140k for the third week,and 90-100k for the 4th week!450k-510k...Anyway,that's just a quite a lot optimistic estimation!My prediction is 365k-400k...so 15-20k,170k-190k,110k-120k,80-90k=365k-400k+!
By the way,I expect 420-480k 3DS globally in the week of release of New 3ds,150-160k EU,as I said 170k-190k USA(20-30 rest of Na),50-60k Japan,30-40k row!
