Even if it sold 500 copies on PS3 at 60$ a pop that is still extra money in the pocket. The thing is, it sold a whole heck of a lot more than 500 copies so I don't think Epic is kicking themselves. Having it on more systems is more advertising in itself. More chances for you to see/hear about the game. Had it been exclusive to 360, or without the Gears Beta we could have been looking at an Alan Wake type flop. So to answer your question, No, it shouldn't have been exclusive to 360. Don't even really see the point in asking this question, but whatever floats your boat.
