Wow, Rovio's next game is not an Angry Birds game - though, of course, it does take place within the deep Angry Birds Universe. Bad Piggies stars the hated pig spheres from Angry Birds, and features "all new, never-before-seen gameplay - and not a slingshot in sight!"

The teaser video doesn't show exactly what the new gameplay is, but we'll find out by September 27 at the latest, when Bad Piggies launches on iOS, Android, and Mac. Other versions coming afterward include Windows Phone, Windows 8 and PC. And though specific announcements haven't been made after those platforms, expect to see Bad Piggies in the plush toy, t-shirt, and fruit snack formats soon as well.
