Angry Birds Rio for Android to be an Amazon Appstore exclusive
That's a pretty major win for Amazon, considering how successful the Angry Birds franchise has been. If you're looking for a sure-fire way to attract customers to your new store, there's probably no better way to do it that with Rovio's follow-up effort.
As Mobiputing points out, Rovio's animated teaser for Rio announced a launch date of April 15th. If that still holds true, it's a pretty good bet that the Amazon Appstore for Android will be open then, too.
