TweetDeck has just released a statement saying that Twitter will be discontinuing several of its apps. TweetDeck for iOS and TweetDeck for Android will be removed from their respective apps store in May. Along with those apps, TweetDeck AIR will also be removed, and Facebook integration will cease. All of the apps will stop functioning shortly after they're removed from the market. They state that the reasoning is because most of its power users only use its web-based app.
