After some googles, i found this site, with lots of info on Platinum, and a japanese trailer!
There are some pictures too, but these are the same as the ones that already where on the internet.
Lucky peoples in japan can play a demo...

 

Thought that already, but couldn't find it with search.

 

If you mean that one... After reading 2 pages, i thought there wasn't any info at all... Well anyway, i'm going to read all the pages.
