I'll put some other big US launches for Wii U games
New Super Mario Bros. U- 266,000
Super Mario 3D World- 144,000
Mario Kart 8- 415,000
And now I predict
Super Smash Bros. for Wii U- 900,000
What do you think? We'll find out when VGChartz updates their sales in the next week
Edit: I'm adding Super Smash Bros. for 3DS for comparison
Super Smash Bros. for 3DS- 558,000
