A NeoGAF member has posted the Japanese packaging for Super Smash Bros on the Nintendo 3DS. The details on the back of the box state that the file size will be 2.1GB which falls in line with other Nintendo 3DS titles. The next entry to the Smash Bros franchise launches first on the Nintendo 3DS on October 3rd.
Honestly I find that’s a bit small. I was thinking 3GB to be honest.
