The upcoming remake of Oddworld: Stranger's Wrath is exclusive to the PS3, but not by choice.
Just Add Water wants to bring its remake of the original Xbox's Oddworld: Stranger's Wrath to the console's bigger brother, but according to restrictions it just isn't possible. The studio recently explained the issue due to a steady stream of complaints coming from gamers about Stranger's Wrath being exclusive to the PlayStation Network.
Just Add Water says that it can only take so much of comments such as "Please don't be dicks, support 360." The truth is that the studio's members aren't being "dicks." If anything is being a dick, it's the size restrictions of Xbox Live.
Microsoft raised the size limit imposed on Xbox Live Arcade titles to 2GB last year, but JAW says the remake of Stranger's Wrath comes in at 2.1GB "without any updates." The 2GB limit is reportedly a limitation of the Xbox 360 hardware, and not an artificial limit such as those previously imposed by Microsoft.
Just Add Water has significantly increased the graphical quality of Stranger's Wrath to bring it up to current-day speeds. For example, the original model of the game's main character used 3,000 polygons, while the PS3 model uses at least 20,000. Just Add Water says it is working with Microsoft to get the game on Xbox Live, but that the final decision isn't up to them. As the 2GB limit is said to be hardware related, Just Add Water admits it has to pull off a "miracle."
But rest assured Oddworld fans, Just Add Water is not an exclusive developer in any way, shape, or form. It hopes to support the PC, PS3, and Xbox 360 for all future releases if it can't with Stranger's Wrath. The studio has made it known, albeit vaguely, that more Oddworld titles are on their way, including the possibility of totally new games, and they'll come to every system possible.
