Nintendo has reason to celebrate a successful December as its 3DS handheld system has broken the Enterbrain sales monthly record since the start of tracking sales, which began all the way in 1997. The handheld has sold a whooping 1,492,931 units, no thanks to the release of two Mario titles and Monster Hunter 3G, which are immensely popular at the moment. Both Mario games (Super Mario 3D Land and Mario Kart 7) have sold over one million copies each in its lifetime, a great accomplishment.
Strangely enough, the Playstation Vita is in fact the second best selling hardware in December, despite only being available since December 17 and pulling in what people call abysmal sales figures (even proclaiming its doom after only three weeks on the market). It has sold 402,794 units in the December period. The Enterbrain tracking for December runs from November 28 through to December 25 and the figures usually differ to the Media Create figures. Looking at that figure, it is quite impressive, seeing that it was only on the market for eight of those days in the tracking period.
