Actually, according to the EA press release we just received, the demo for Army of Two: The 40th Day will be released in significantly less than 40 days. It'll arrive on the PSN and Xbox Live Marketplace on December 17, and the PSP demo will drop on January 7 (January 14 in Europe). The preview will allow players to get a sneak peek at most of the game's first level, which takes place in Shanghai -- but you know what? None of that is important. What is important is seen in the trailer for the demo, which we've posted above.

Now, jump to a little bit before the halfway mark, and keep an eye out for the strange interaction between the game's two beefy protagonists. What is that? It's like ... the future of fist-bumping technology. The forearm-bump. More subtle, yet still triumphant. Less aggressive, but still dripping with bravado. An alternative manly salutation or congratulation for the gentleman's mercenary. Study the technique, friends. This thing's gonna catch on like wildfire.
