GenDesign, Fumito Ueda’s new development house, seems to be teasing something on its website home page– a mysterious new bit of artwork has gone live on the site in commemoration of the new year, showcasing, among other things, some doves, a girl on an altar, and what seems to be a giant creature of some sort- all of which seems to be right up Ueda’s alley.
Ueda-san’s previous game was The Last Guardian, which launched last year exclusively on the PS4 after a decade of protracted development; he is known for making exceptionally well received games, including ICO and Shadow of the Colossus prior to The Last Guardian.
As for what this art is teasing- it could be an all new game. It could be absolutely nothing. Personally, given his track record, I hope this means that Ueda-san has started work on a new game- I also hope that this game is out sooner rather than later (for all his genius, he isn’t known for sticking to deadlines).
