Capcom US has seemingly acknowledged that a PC and 360 game called Lost Planet Colonies is being prepared.
The game has now shown up on the websites for a couple of ratings boards, including the US ESRB, and the publisher told IGN to "stay tuned".
Capcom Europe said it couldn't comment.
There's no word on what exactly it is yet, but speculation that it's a sequel - perhaps to be unveiled at GDC - is rife.
More likely is that it's just a special edition that does what the upcoming PS3 release does - rounding up all the available DLC and patches - but it sounds like we will have to wait and see.
The PS3 version of Lost Planet is due out here on 29th February.
