Well, I guess it can hit the Million-Border easily. Why? The more Wii Us sold, the more of the older games will sell. We saw it with ZombiU. When Pikmin 3 came out, Zombi U is since then making an appearance every week now in the US. And don't forget about the Lego City Undercover Bundle in Europe!
It was a lot of fun that I had with this game. Frank Honey was absolutely funny. For the sequel I wish the cars would have more differences in speed an other stuff like this.
