I was looking this up as well the other day. How reliable is that website? I heard that they were not even sure if they were gonna release it on PC at all... I'll be real annoyed if they don't :/
I've never heard of it before but that looks like a cool site.
It does say rumored however it cites where it got the info (http://www.worthplaying.com/article.php?sid=57828) which of course cites another "reliable source". I guess its hard to tell but at least its some sort of estimate that a few lesser known sites claim came from "reliable sources"
I poked around a little and haven't seen anything else.
