The following comes from Regista, the visual novel studio behind the Root Double series and the Nippon Ichi Software-produced Exile Election.
“The limited company Regista will develop for Nintendo Switch. We are starting work on the development of existing titles, as well as original titles. Please look forward to the announcement of more information.”
Looks like there will be ports and new content, so the best of both worlds! Let's hope some of these games get official localizations.
