Man, Reddit Ask Me Anything posts are becoming a really great source of developer feedback. This time round the topic is DayZ, and it's Dean "Rocket" Hall who is answering the questions. According to him, the standalone version of DayZ will be available in Alpha, "Minecraft stylez", before the end of the year. And yes, the team plans to address the hacking situation.
"[H]acking is an ongoing issue," said Hall. "ArmA2 was never designed for what DayZ is putting it through. With DayZ standalone we can address this issue without causing ArmA2 problems, so it can remain the product it is. It is something we will always have to work on, you cannot completely stop hacking."
The team intends to release the game in Alpha, and continuously update it, ala Minecraft. According to Hall, the team is hoping to release the game before the end of 2012.
"Alpha will be heavily discounted paid project," he explained. "The project will never be a full retail priced title, and the alpha will be heavily discounted. No prepurchase. But there will be a premium type purchase that contains some extra collectors edition type stuff like concept art prints etc... for those who want to throw money at the project."
For more information, it's well worth heading to the Reddit page itself. There are some great insights there.
