For those of you sitting at work, unable to surf the full web, here - as the title may hint - is the new MGS4 trailer, shown off at the Leipzig Games Convention. It features the most exciting use of a bulldozer yet witnessed in the Metal Gear franchise. Oh and some of the new boss characters. From today's press release:

"The characters - Laughing Octopus, Raging Raven, Crying Wolf, and Screaming Mantis - are empowered with special, supernatural abilities and have individual back stories that outline how they have become the beings they are. All were initially good people who, for various reasons linked to events in the Metal Gear Solid series and events they have seen in countless wars, are now altered beyond all recognition both physically and mentally - and are perfect examples of the 'Beauties and the Beasts' themes that run throughout MGS4"

So I think I've figured out who Laughing Octopus is, but can you place any of the others?
