PS3 games can be PhysX enabled, so that indicates nothing.
In fact, there are other PS3 games listed on the site (Valkyria Chronicles) that are never hitting PC, so the list indicates nothing other than what it says- PhysX enabled games.
It's not coming. It is a really good game, though, in terms of story-telling.
EDIT: I realize it lists "PC" next to the game...interesting, but I'd suspect that it's a mistake. Could be wrong, though.
