Fruit Ninja has grown into a wildly lucrative property since first sprouting up on the App Store in April 2010. It's since branched out onto Android and Windows Phone 7, and its first true offspring won't fall far from the (money) tree.
Fruit Ninja Frenzy will be a free-to-play Facebook game and is currently in development with no confirmed launch date. Halfbrick says Frenzy will offer "60 second gameplay with many powerups, unlockables and achievements," and will lean on a collectible in-game "juice" currency, which players can purchase with real money.
Halfbrick promises that beta tests "will be announced soon."
