Only days after it launched a new Mine & Dine update for the original Angry Birds game, developer Rovio has announced via its Facebook page that Angry Birds Seasons for iPhone will also be getting an update.

The Finnish developer has kept mum with regards to detailed information on the Summer Pignic update, with only a couple of images shown on the very same Facebook page.

When pushed lightly by users on Twitter, though, Rovio intimated that we'd see the next episode in the Angry Birds Seasons saga on 4th July.

Looks like an Independence Day special for everyone's favourite frustrated fowl!
