We currently have no plans to bring our apps natively to the Playbook at this point. I want to see how well the simulator for native BB apps will work on it. If it turns out the device is popular and the simulator isn't great, we would reconsider that decision.
Is the beta still available for download? The link on the first page doesn't work.
From Epic's last couple posts, I believe the beta link is dead. It was only for 3 levels btw.
Once the release version is available in App World, there will be trial version available there too. I'm sure there will be an update in this thread when that happens too.
