First it was, then it (maybe) wasn't, but Famitsu (via Andriasang) is reporting that a remastered version of Okami is coming to the PS3 this November. (Update: Capcom has now confirmed it.)

The game will feature PlayStation Move support, have trophies, and support full 1080p HD.
 
There's no word yet on the North American release date (apart from "this fall"), but we do know that Okami HD will be a $19.99 download on the PSN. Hopefully this time around Capcom springs for non-watermarked cover art.
