During the latest Sega-nama livestream (akin to Sega’s version of a Nintendo Direct), Chief Creative Officer Toshihiro Nagoshi made the announcement that the company has been working on something new, and to expect a further announcement sometime in September.
Although few details were mentioned, Siliconera highlighted a few key details: Nagoshi indicated that the announcement would take place somewhere around Tokyo Game Show, which takes place September 19-23. Whether this would be part of a conference or whether Sega is planning a separate event isn’t something he’d be drawn on, saying only that the announcement will take place “before the next Sega-nama”, which is at the end of September.
