Like every other Metal Gear Solid game, a great deal of Portable Ops is being kept away from prying eyes as to not spoil the important storyline aspects. But just the thought of a full-fledged console-quality Metal Gear exclusive to PSP is a mouth-watering proposition, and the hook of being the game that effectively ties the Big Boss games with the Solid Snake games makes for a game that will wind up being very important to the Metal Gear saga. It could ... be a killer-app that can sell PSP systems when it ships sometime in 2007, giving Sony a bit of a boost in the portable marketplace. So while it's a-okay to hype MGS4 to the hills, don't forget the little guy, and don't forget the newest adventure of Big Boss.
