This rumor comes to us from Pocket Gamer.
According to them, the Valentine’s Day Edition of Angry Birds will have players popping hearts to earn them extra points in the levels, similar to the way Angry Brids Halloween featured pumpkin popping.
They also say that a brand new bird is in development for the Valentine edition, although there are no solid details yet.
None of this has actually been announced though so take it with a grain of salt for now. But it definitely sounds plausible, as developer Rovio has had success with their two seasonal updates so far. So it only makes sense.
