Angry Birds maker Rovio looking at $1 billion IPO next year

Thanks to those irate, wingless birds, Rovio is worth lots and lots of money, apparently. Speaking with Bloomberg, the Angry Birds creator's CMO Peter Vesterbacka said, "We're not ready to file for an IPO tomorrow. Maybe a year from now." And speaking to the recent estimations that Rovio is worth around $1 billion, Vesterbacka all but confirmed the guesswork.
