I'll play it eventually (though I'll probably end up watching the entire story on Youtube first) but I really wish Kojima would make a non-MGS project for once. Metal Gear Solid is great, but the series wrapped itself up well enough with Guns Of The Patriots imo and I don't really care to see this story dragged out even longer than it has been already (especially if it's just gonna be more of Big Boss' story instead of Snake's.) Kojima is really gifted when it comes to the art of storytelling (although he could really use an editor at times), so I'd love to see him put it to use in a whole new project.
At the very least, if he was gonna do another MGS project, at least do a 'remake' of Metal Gear 1 and/or Metal Gear 2. An updated version of Snake vs Big Boss in Outer Heaven and/or Zanzibar Land with new and improved graphics/gameplay mechanics would be awesome, and diehard MGS fans like myself have been asking for it for a long time.
