Last Year 3DS managed to sell only in November + December 1170k.
Now you will tell us that a New Revision + the Trinity (MH4G, Pkmn OR/AS, SSB 3DS) + the New Friend (Yokai Watch 2) will not match this sales?
If i add October to that last Years Sales we look at 1768k for 3 Months. The relese scale is the same like last Year + we have a Revision and the Big Hitters are releasing later (in favor for the n3DS).
I don't know.
3DS sales are declining YoY and Pokemon OR/AS+MH4G are a lot less important than Pokemon X/Y+MH4 as I'd expect that they will attract less new users on the platform.
Also, New Friend (YW2) is surely strong, but also last year's New Friend (Puzzle & Dragons Z) and Old Friend (Tomodachi Life) were pretty strong. And 3DS closed the year with Zelda LBW.
OG 3DS/LL won't be retired from market, so I think that price promotions will let them steal few units from n3DS YTD. Same with Smash Bros. WiiU that could steal some of 3DS version's thunder.
I still think that 3DS could lose something, despite the new revision, but I don't know how it'll be received. If it'll explode then they will do high numbers like last year.
