In two words, chip size. The DSLRs you mention have far larger chips than the average $10,000 camcorder you talk about, and generally use either prime lenses or zooms with much lower ratios than most video cameras - hence keep a reasonable size/weight/cost. Build a camcorder with a single chip of the size of that in a DSLR, and with the features most people expect in a video camera (such as at least 10x zoom) and it would be big and expensive. Simpler generally to use three smaller chips.
You can get small cameras with single chips - but they are inherently less sensitive than those with three chips of the same size (all else equal).
