The Japanese Nintendo site Nintendo Dream recently published information interview with a number of staff working on this year's fun Mario & Luigi: Brotherhood for Nintendo Switch. Mario & Luigi: Brotherhood co-producer Akira Otani was one of those interviewed and revealed that the team had initially settled on the name Mario & Luigi: Wonder, however, that plan naturally changed when Nintendo revealed they were working on Super Mario Bros. Wonder, so the name change was in order.
Otani: Actually, I was going to add Wonder at the beginning. Like “Mario & Luigi RPG Wonder”. But while we were working on it, the first to come out was “Super Mario Bros. Wonder” so we couldn't use it (laughs).
Thanks CM30 for sending the news notification!
