The ESRB has slightly modified its Silent Hill 2 page (via Insider Gaming) to state that it's certified for the "Xbox Series" consoles. The rating itself hasn't changed, and it's still M for Mature. However, Microsoft and Konami have yet to formally announce the port or set a date for it. We can't even say for certain if Silent Hill 2 will get a physical release on Xbox, or if it will be digital only.
We didn't want to just announce a single remake to 'test the waters.' We wanted people to feel how serious we were about reviving the series. Developing a remake and a new title simultaneously naturally involves risks, but we wanted to convey our commitment first and foremost. Only when a new game is announced can the future of a series be seen.
