Yeah, I love Tetsuo: The Iron Man. Didn't like the sequel much though. I'm hoping part 3 gets it right again - the trailer at least makes me have some hope.
This is Tetsuo, so the trailer is probably NSFW. This is the Japanese trailer.

I'm of the opinion that shooting the film in English with Japanese actors is a bad idea (though the English in this trailer isn't too bad), but we'll see where the concept is going. It's playing in theatres in Japan this month.
Looks interesting, it seems to have the stark flavor of the original. I have really fond memories of seeing Tetsuo in a theater 20 years ago, it has my favorite title sequence in all of cinema, and Chu Ishikawa's soundtrack is very powerful. Tetsuo II: Bodyhammer I have not seen in at least 16 years, so I do not remember that film very well.
I really want to watch the trailer, but I think I need to watch Tetsuo 1 and 2 first. God knows I've wanted to...
