As if its flock of angry fowl weren't already near-ubiquitous, Rovio's today announced an August 13th release date for the Wii and Wii U versions of Angry Birds Trilogy. The Finnish company had previously committed to the two Nintendo ports earlier this year, prompted by the success of the title on the 3DS, PlayStation 3 and Xbox 360. Rovio's not just pushing out a repackaged redo, either -- this collection bundles the original Angry Birds game with Seasons and Rio, while also adding some new levels. And given the finger-flicking origins of the franchise, gamers will be able to make use of the Wii U's GamePad for that famed asymmetric play (read: GamePad-only) and touch controls. If you haven't already exhausted your lust for flipping Rovio's birds, then the dog days of summer should see you and that Wii U making nice. Of course, by then you could also be flinging zombie-like Pikmin with reckless abandon. What's a Wii U owner to do?
