Coming soon to the PSN for $20 is Okami HD, an upgraded and polished re-release of one of last gen's most critically acclaimed titles. A translation of the Japanese announcement for the uniquely artistic action game says:
According to the blog post, the game will have HD visuals, a 16x9 aspect ratio, and PlayStation Move support for making your Celestial Brush strokes. Trophy support (including a Platinum Trophy) will also be included.
Take a look at its beautiful style in this trailer (be sure to manually switch to HD in YouTube first). The second half shows examples of the PS3 vs. PS2 improvements.
