UPDATE - The page has been taken down by Nintendo. Also, it's worth mentioning that this might have been a mistake, as the info on the page matched up with a listing of DLC for SNK Heroines.
Here's a bit of a rumor for you about the future DLC for Smash Bros. Ultimate. Wondering who's going to be in Challenger Pack 4? According to the Nintendo UK hub listing for the pack, the character is going to have ties to SNK. We know this thanks to a mention of SNK on the hub page.
Could this be a mistake on Nintendo's part? It certainly could be, and it's likely the info will be removed soon. I guess we'll find out for sure when the next Smash Bros. Ultimate character reveal trailer rolls around!
