And here's the SSB4 Bingo Infographic. Using the SSB4Bingo cards as a survey, I tallied up all the character selections and figuring out which characters people think are most likely to be in SSB4 took a bit, but I also found out some interesting things, which I think you guys will enjoy.
Feel free to ask me any questions about it, or about anything I haven't included that you would like to see included. I will of course update this as more cards are created and characters revealed.
Also I wouldn't recommend taking any of these as a guarantee that any of the "Top 10" characters are going to appear in SSB4, these are just the ones people want the most, but popularity doesn't hurt in this case.
