The industry insider Marcus Sellars, who was quite right with his statements (if not always), has learned from his sources that “Super Smash Bros.” for the switch will offer a two-player co-op story mode, which would certainly be an interesting feature.
But i independently verified that info with my own sources. All the other other info he gave me I knew was fake. That's why I didn't post about it.
Hope that clears things up.

In addition, many third-party companies should be represented with their characters. As for Nintendo, the “Ice Climbers” will be on board this time, according to Marcus Sellars. For rumors, of course, always that they should be recorded with the necessary care.
