Metal Gear Solid Touch dives into the world of the PlayStation 3 smash Metal Gear Solid 4: Guns of the Patriots, linking the iPhone game directly to the main series. This is not some goofy off-shoot. This is canon. The arrival of Metal Gear Solid on the iPhone is not small potatoes. Konami saw fit to get Snake on the App Store before the Xbox 360. Think about that when you're wondering which gaming rig is positioned for a strong 2009.
