It's a bit hard to predict, Galaxy did almost 10m and Galaxy 2 almost 7, Mario 64 was the only 3D Mario on a handheld and it did above 10m if I remember correctly, so this should do like 10m or somewhere close, if 3DS sales go as high as the DS it can surpass that as it's a new game and not a remake as Mario 64
don't mind my username, that was more than 10 years ago, I'm a different person now, amazing how people change ^_^
