That quote from November is cool and all, but I think you’re forgetting the recent QA post by James.
Q. How soon do you envisage it will be that the new blocks will ‘out-grow’ the current server builds. Basically how long until we need new worlds to play on?
As above. After the C++ release we’ll be working on a set of core economy features including: storage, locks, trading, recipes, initial guilds, currency, shops and initial player progression. These work alongside the wrapping worlds, world regeneration and resource regeneration to create a viable player economy and ecosystem. This update will also contain our best effort at 1.0 blocks, minerals and resources. All this together will require us to deliver a new set of worlds for you to play and experiment within.
Q. when will the first server wipe be ? (some time ago i read the migration will be over time, not all servers at the same time)
Once the economy features are solid we will take the current worlds offline. We will give plenty of warning about this. To confirm, the worlds are being taken offline - not deleted. The new features would not make sense on the current worlds as they lack all the resources and blocks required for the crafting and recipe system.
Q. when can we expect the first new worlds ?
The C++ version of Boundless will be released initially on the Steam beta channel and will give players access to an alternative universe of worlds. This is because the C++ version is already starting to include some of the new economy features and assets, specifically in the area of worlds generation.
AKA, we’re getting new worlds with the C++ update and old worlds will be going offline soon after. Now how long of a time is “soon after” is up for debate, but I think most people are just waiting for the new worlds to come out to be safe with any new projects.
