Future Weapons?

Last night I was watching the Discovery channel show Futureweapons, and there were a couple of things that had me curious.

First, the new body armor Dragon Skin. I believe that has already started to be issued to Marines. It looks to have been inspired by Samurai armor of overlapping plates, but in this case the plates are a combination of ceramic and titanium. In the show they fired at it from what looked like about 10 meters with .556, .762 and 9 mil ammo. They also put it on top of a grenade and set it off, and the armor came through all those tests with flying colors. My only question is will this armor work like Kevlar, where it stops the rounds but turns everything under it into strawberry jam?

The second thing was a suitcase-sized shaped charge that can be placed under a car and use water to blow the ammo right out of the trunk. Of course, first you have to get it placed, then hope that you don't have a suicider in the car or an observer to set off the bomb first.

Finally, I'm in love. My favorite weapon was always the M-79 40mm grenade launcher. Now they have the M-32, which holds a 6 pack of 40mm rounds. Besides the normal HE shrapnel round, they have infrared ones and flares to light up the field. I'm assuming that Willie Pete and Beehive rounds will be available (as long as no one tells Geneva).
