Dan Houser and Leslie Benzies have on numerous occasions declared their allegiance to Sony... Sam is the one whose all peace-love-&-happiness when it comes to the "console wars". It was his decision to make GTA III a multi-platform title (although Dan wanted the game out on the PC as well... don't remember where I heard that but I definitely remember reading that they had a quarrel). I agree that the xbox is easier to develop for, there's no arguing there, but there's developers out there who simply don't like the xbox. Leslie Benzies and Hideo Kojima come directly to mind. But then there's plenty of developers who are loyal to xbox so that debate could go on for years.
Side Note: Someone just told me earlier this afternoon that she'd heard that Remedy is going to make a new Max Payne, and it's only going to be on PS3. Why on earth would they do that? Here's something you'll NEVER SEE ME DO AGAIN... stand up for the xbox. Max Payne sold more copies on the xbox, didn't it? And didn't MP2 NOT sell that well (probably due to massive amounts of suckage)? So why would they make a third one, and if they're going to, why only release on the PS3? It seems kinda silly, even to a massive sony fan like myself
