While the game's only been announced for the PlayStation 3, JAW's clarified that no money's been placed on the remake's head — no, it's simply a limitation of file-sizes allowed on Microsoft's XBOX Live Arcade service.
Now with regard to Oddworld: Strangers Wrath on the 360 there are a number of factors that are currently sitting in our way to announce a 360 version of the title, whilst we cant go into all the details, what I can say is we are working with Microsoft to get the title on that platform, however the final decision is NOT ours, reads a blog post by the studio.
One thing we can discuss in regard to the 360 version is the size of the game. On XBLA there is a 2GB size limit we have to adhere to, currently the title weighs in at 2.1GB and that is without any updates, so either we have to pull a miracle out of the bag with some type of amazing compression system, or ask Microsoft to increase their 2GB limit, however this limit is apparently hardware led, so please let us try and make a miracle happen.
So technically it's not an exclusive at all. But the good news for PlayStation owners is that we're definitely getting the game. Seeing as we've never played it here at PushSquare towers, that's rather exciting. And to be honest, the only thing that matters.
