Blackberry and Unity have announced that anyone who subscribes or purchases Unity Pro (not just Unity5) will now gain free access to Blackberry development tools. The addition will be available to all Pro users the next time they update.
This move puts development addons for Unity along with Windows Phone 8 Pro and Windows Store Apps Pro as free addons for Pro users of the engine. iPhone and Android addons remain unchanged at $1,500 additional cost on top of the price of the engine itself.
