Although it's not mentioned in the article, Gibson is actually just the distributor for this system. It was actually developed by a German company Tronical (http://www.tronical.com) as the PowerTune system which is designed to be a retrofit to *any* guitar. Gibson secured the worldwide distribution rights in early '07. The system is actually capable of doing several different tunings (not just standard), however, you can't tune and play at the same time (you need to strum the open strings, press a button then wait a couple of seconds for the instrument to retune).
