Apparently those MK7 figures are conservative estimates. It may have sold bit more: http://andriasang.com/comz7u/3ds_mario_kart_surge/
Few quotes form article:
"The 420,000 unit figure we gave for Mario Kart 7's sales earlier today was apparently a conservative estimate. Sinobi reports a more precise figure: 451,932 units."
Also for 3ds
"Retail blog Sinobi reports that 3DS sold 216,350 units last week,"
But this thread is for media create's numbers so we'll go with that.
