The company announced on Twitter: "Big new game announcement coming on Monday! #July15"
Ignoring the incorrect use of a hashtag there (#pedant), the tease also included the image found above. The picture is based off the iconic, evocative teaser that got us all so excited for Star Wars: Episode 1: The Phantom Menace, before our dreams were dashed by the realization that the movie was a steaming pile of bantha poodoo.
We've placed the Phantom Menace image after the break. The new Angry Birds game will be announced next Monday.
