A Digital Illusions press release - in Swedish - announcing Battlefield: Bad Company that's appeared on the developer's website seems to confirm that the game won't be limited to next-gen consoles.
Bad Company's already been announced for PS3 and Xbox 360, of course, but in the press release we're told - according to translation - that "More information about the PC and PSP versions will be presented at a later time". Obviously, the PSP Bad Company experience would be somewhat different to that offered by its next-gen console cousins, but it sounds like PC gamers are in for a title tailored a little more exclusively to the platform as opposed to a direct port - although that is speculation.
