A Sega release schedule appears to have outed an HD remake of the first two Yakuza games. Yakuza 1&2 HD Edition appeared briefly on the schedule, listed for PlayStation 3 release on December 1 at ¥5,229.

While the game is no longer visible on the schedule page, you can see a cached version here.

A December 1 release for Yakuza 1 & 2 HD would mean a crowded month for Yakuza games, as Yakuza 5 is also due for release in December.
