Pre order thoughts

More & more over the last several years are these (tech)? companies announcing upcoming new products, then demo-ing them live, then they tell us that they can start being pre ordered in the next week or two. Is it a way to test the markets reactions to the new products, or some other reason(s).

Just my pet peeve I guess... why not just wait an extra week or two to demo the product, when its actually available.

Any thoughts or opinions out there?

Cheers
