We've already seen some of the product placement to be found in the soon-to-be-released Metal Gear Solid 4, and it looks like PlayStation 3 users are in store for a bit of reinforcement about their console buying decision as well. As you can see for yourself in the video after the break, at one point during the game, Metal Gear Solid's Otacon takes a not-so-subtle dig at the Xbox 360's non-HD disc format by asking you to swap disc 1 for disc 2, only to suddenly realize that you're using a Blu-ray disc, and a dual-layer one at that, which then prompts him to go on about "what an age we live in." At least there's no HD DVD reference to further rub it in, though we wouldn't doubt that there's one of those lurking somewhere in the game as well.
