You're probably going to get Metal Gear Solid: Portable Ops anyways, but if for some crazy reason you're still on the fence, Konami has offered one of the cooler pre-order bonuses I've seen in quite some time. Pre-order the game at Gamestop and you'll get a case for your system for free. Not just any case, though. A pretty spiffy-looking silver case with the image of Snake giving a salute. This is some classy stuff, and is sure to be as eye-catching as the $500 Signature Edition PSPs.
