The feature, Nikkei elaborate, will allow you to swap between different games from the system’s main menu. While we’re tagging this a rumour, Nikkei are usually spot-on with their Nintendo predictions, so don’t be surprised if this is true and Iwata and Reggie simply didn’t mention it at their press conference.
