Today we learned that Facebook and Flipboard will be getting "official" apps for Windows 8. Indeed, Flipboard has confirmed that an app will come out this year. Yes! But all its got to show so far is an 8 second prototype animation.
More official apps for Windows 8 is important because developers have been hesitant to jump on board when they can just build web-based versions that work across platforms. Now these apps are "official". We don't yet know if that means "official" built by the companies or "official" built by Microsoft to bolster the ecosystem. For now, it looks like "official" not really existent yet.
