People have been theorizing that arrays are the future for more than twenty years, but now I see some real progress. There is some very interesting work in Germany now for almost a decade with real industrial applications. I think you will start to see some useful products that move beyond theory. Whether they put it in a camcorder is another story. Manufacturers deliberately put crap audio in the camcorders so they can sell accessories. For $20 in parts they could put five "Zoom H2 or better" capsules in a camcorder with 24 bit audio and surround option. But they don't do this, of course. Look for an "add on" mic with somewhat better capabilities, or for a second tier like JVC to make the jump before Canon and Sony.

One of the simplest arrays is the rubber band combo. For example, take two pairs of of omni and cardioid, or omni and hyper, and tie them together with rubber bands, so they act like one mic but do not vibrate. Then you have a virtual mic with different colors, even more flexible than the Sennheiser MKH 800 twin if you use mics with interchangeable capsules. You can also take a dual capsule mic and wire each capsule separately and create your own Neumann type multipattern, but the rubber band system for now is the fastest and cheapest way, and you can tie even eight mics into 4x2 or 2x4 arrays.

One array I like very much is tieing a Sennheiser MKH40 with a Schoeps MK2H or a Schoeps MK21. Also the Schoeps MK41 tied to a DPA 4003.
