The demo explores the environment Snake will be operating in, as well as the many new game features explained in the video such as Snake-Eye, Octocamo, new targeting system, new movement controls, the improved CQC from the previous game and many other snippets.
There's little point in me describing what happens in the video, as Hideo himself does a pretty good job on the running commentary (the subtitles, because as you may have guessed, he's Japanese).
Certainly one of the things that will strike you ahead of previous MGS games is just how intense the battles are. MGS has always been a stealth game, and it does continue that way in the 4th installment, the only difference is that you are infiltrating a warzone and the gameplay is designed to have you cope with a live battlefield environment.
The vast array of new controls is also impressive. Snake now has the lowered stance movement available, instead of just crawling on his stomach. Also, thanks to the SIXAXIS, the game can be played as a FPS (First Person Shooter), similar to how the earliest trailers of the game suggested the gameplay might be like.
I'll leave you to make up your own thoughts on the video, so do leave a comment if you've anything to say about it.
The second trailer is back to a real-time movie standard, entitled "Beauty and the Beast". The trailer reveals four of the bosses that will appear in the game.

Several things make these bosses special and unique, compared to previous bosses. Firstly, they're all women. Not that that's a bad thing or anything. Each of them was modelled on a real world (fashion) model. Previously the boss "unit" in MGS featured both men and women. Secondly, this is the first game to feature bosses that are -mainly- mechanical, although they're female form (aka the Beauty) is underneath the mechanical form (aka the Beast).
Thirdly, on initial inspection it would seem that each of the bosses is named after bosses from the first Metal Gear Solid: Decoy Octopus, Psycho Mantis, Raven and Sniper Wolf. HOWEVER, on looking at their names, it seems as though Hideo Kojima has also named the four women after the bosses in MGS3. Although I haven't covered this game yet, four of the bosses in MGS3 are named: The Joy, The Fear, The Fury and The Sorrow. Now, take into account the human response to each of those names.... Joy = Laughter, Fear = Screaming, Fury = Rage, Sorrow = Crying. Therefore, we can conclude that the names of The Beauty and the Beast unit are derived from both MGS and MGS3, thus showing another aspect of Hideo's creative genius and also his cleverness to incorporate minor references from the previous installments.
Enjoy the video. Speaking strictly of gameplay terms, these bosses are going to be a biatch.
On one final note, Hideo Kojima confirmed in person what we all hoped and that was that MGS4 is in fact PS3 exclusive!!!!
