Wow. That. Was. Fast. It's been out for, oh, a day, and already a LostWinds sequel is on the way. If you pop on over to Frontier Development's website, and scroll down to the bottom of the page, you'll be greeted by the following message:

Yes, OK, the "sequel" has obviously already been made (or is at least a good ways along), but good news is still good news, regardless of how surprising or unsurprising it may be.
