You're forgetting an important point from the business perspective. It's also a very worthwhile opportunity to relaunch your product, makes it more appealing, revive interest and initiate a marketing blitz to generate attention and, hopefully, even more sales. Especially if it's a popular product.
One such relaunch catapulted the PS3 to very good sales. The first revision actually saved the console, I would say. PS2's revision though, that made the console go even further to become the best selling console of all time, as it was already the undisputed king of its generation.
