There's a steam boat, but no sign of Sasuke, the clockwork robot ninja who pals around with Goemon in the video games. (Sasuke has a switch that flips him between good and evil, which is awesome.) Or Goemon Impact, the clockwork robot version of Goemon.
The movie definitely has an urban fantasy-ish spin, but it's hard to tell how steampunk it'll actually get, since no details have leaked out yet. [Loyal KNG]
