I'm not sure how long it took MH4G to reach that spot on the chart, but MHX reaching it in only 3 days is something else. There are stock issues at retail but even then, wow.
Also, Mpl90 reported earlier that back when it was #18, since it outdid Gunman Clive, it was at least at 140k copies sold on the eShop about 12 hours earlier:
Well, the sold out is helping downloads: the game's already 18th in the 3DS eShop All-Time Chart. Thus, since Gunman Clive is outside it, it's already over 140,000 digital copies sold, at least.
