The Wii U sold 106,986 units WW the first week that SM3DW was released. SM3DW's preorders were at 96,619 in the U.S. during it's final week. That was during the holiday season when sales are usually up.
By comparison, Mario Kart 8 is currently at 175,476 preorders in the U.S. with 3 weeks left. I expect it to be at at least 240,000 preorders during it's final week. That's more than double what SM3DW was doing, but I don't think hardware sales will match or surpass holiday numbers.
