the 1Ds does lock on a subject and track its motion provided that it stays 
under any one of the focus points. it will track a moving bird or football 
player provided that you aim the camera roughly aimed correctly. no Pentax 
camera does this well enough to really useful, but the Canon 1D system does.

I agree.
But my point was that there's no locking on to the subject. It's just the
focus system "catching" whatever comes by, close to the previous focusing
distance. If I was photographing a group of kids running at the 
playground,
the camera might catch a girl, then a boy, next time a dog or a bird. 
There'
s no locking onto anything. I don't believe any mass produced camera 
system
can do that.
