Nintendo comments that Zelda/Mario team is “hard at work”

During their E3 press conference (which seems to be sadly Reggiless), Nintendo has commented that the developers of Zelda and Mario games are “hard at work” on making “new titles”. Regretfully, the company did not reveal any new game to accompany this announcements. However, the conference is not fully over at the time of writing this, so anything could happen.
