The last game had a max of 4. We currently have 5 characters in from the Mario series. It's unlikely they'll jump to 6 right away. 5 characters from the main franchises just feels right. And remember, this is my prediction list. You can make your own if you wish, and you can put in as many characters from any franchise you want. I tried to go for a little balance.
