Angry Birds Trilogy slings onto Wii and Wii U August 13

The Angry Birds franchise seems keen on flinging its poultry all over the place, and Rovio has announced the release date for yet another pair of platforms. The Wii and Wii U versions of the Angry Birds Trilogy will hit on August 13, according to a new trailer for the games.

The trailer showed plenty of birds crashing into things, like you do, but curiously no showcasing of either console's unique features. The previous announcement didn't mention those features either, so we're still left at a loss of what will make these versions stand out. The trailer does, however, promise an additional 40 hours of gameplay, which is a lot of bird-flinging. Maybe too much
