Amazon 3rd Generation Kindle Already on Back Order, But Not Even Released Until September

It seems like a lot of gadget manufacturers are focusing on bringing out new models as fast as possible, without even building up stock in the meantime. The latest is Amazon and their Kindle product. The Amazon Kindle is expected to launch a third generation in September, which already seems to be on back-order.
The third generation Kindle was planned to be released on August 27th, with both a Wifi and 3G version. Currently, both WiFi and 3G versions of the new Kindle are now listed as “temporarily sold out” with new orders not likely to ship until September 4. If these pre-orders continue to come in in excess of Amazon’s manufacturing capacity, we may even see that date slip farther back.
Is this the right practice? Or should these gadget manufacturers be focusing on building up stock and then announcing pre-orders. Its of course very difficult to expect what demand a certain product is going to have, but this becomes a lot easier when it is the third generation of a specific product.
