Personally I think that once that the Unity 3d Engine is officially supported by Blackberry Playbook, well will see some killer games finally running! Anyone heard of any news about release dates, or when the "BIG" playbook update is expected?
Unity has stated that if you sign up for their game distribution platform "Union" whereby they publish your game on various platforms, they will handle the porting the Playbook (for now). I would love to see a standalone exporter in the future though.
