Creator Dean “Rocket” Hall wrote on the Dayz development blog:
“We are still working towards a target for an initial foundation before the end of the year. But we will slip this date if needed, we will not compromise the project for the short-term gain of meeting this date. The reasons for any slippage would be publicly discussed, and would most likely represent a failure personally on my part to plan correctly. We will be assessing the results of our major architectural changes at the end of next week, and reporting the results to everyone when we have assessed that.”
Despite the delay, the development seems to be going strong with the game still going for a release within the year according to the date posted on Steam.
The stand alone will be a completely reworked version of the mod, with significant changes to the engine:
“Due to the success of the development so far, and the interest in the project in general – we decided we want to do things properly. This means we have been very bold with our architectural changes. We are moving to the server-client MMO architecture model. We are making weapons and items ‘entities”, meaning we can support customization and variables assigned against items. As discussed previously, this is a massive departure from the previous engine. In many ways, once this phase is completed – one could effectively say that DayZ is running on a new version of the engine. While the graphics may look the same (for now), under the hood so much is being completely rewritten.”
The game will be released soon enough and once the PC version is released, DayZ might also see a release on consoles. However, the release might be delayed up to 12 months beyond the original plan according to the blog post.
