By now you will have heard about the first official Angry Birds Day when lovers of that crazy iPhone/Android game come together to celebrate the ongoing war between the birds and the pigs. However, well placed sources told us yesterday that something big was going down on that day, specifically in London’s Trafalgar Square. Now, this is becoming a big venue to launch big games, especialy console games. Here’s the spectacular Halo Reach launch with guys in JetPacks earlier this year.

There is speculation that Angry Birds for Windows Phone 7 will be anounced on the day. There is also speculation that the game’s developer, Rovio Mobile, will launch a games console version or that it will spin out a movie. Actually personally I think that maybe, just maybe, something different is going on. Here’s why.
