Why are people making such a big deal out of this, especially the PS3 fanboys.. They're getting Bioshock, one of the Xbox360's so-called 'exclusives'. So why whine when they might get your precious MGS4. It's not like it's a 1st party title, Konami can do whatever the heck they want and deem smart. It's just business. And after all, making a ton of money for a fraction of the costs is only smart, right?
Also, it can be ported. The game may not come out 100% the same in the end, but that's only natural. Remember people, this is exactly the same as the GameCube's situation with Resident Evil 4 a few years back. So-called 'exclusive' too. Made by a loyal 3rd party. Pushed the powers of the 'Cube to their absolute limits. Well, and where did that game get ported to eventually? Right, the inferior, underpowered PS2. Boo-hoo. Xbox360 and PS3 are closer in power than the GC and PS2 were back then, relatively speaking. So, get over it.
