So map voting has now been announced, info taken from slapshots post in a different thread since I know its correct at the time of me posting.
Here is the info from the Dev Journal:
World Generation is no small task, and is something we've been working on continuously for the better part of the project. But with pre-Alpha once again visible in the distance, and Map Voting and Domain & Settlement Selection rapidly approaching, our need to procedurally create the continents, settlements, buildings, and points of interest has never been higher. So in Release 0.5.0 myself, Souzou, and Raevantiel will be finishing a significant portion of the procedural world-building mechanics in preparation for the launch of Map Voting.
And when is Map Voting, you may ask? Well, as promised in the Release 0.4.0 completion blog, the release of Map Voting is just around the corner. While the news and announcement post containing the final rules and information on the map voting process will be published a few days ahead of it on the 18th, Map Voting itself will begin the 22nd... of October. So, you know, soon™.
But elsewhere Caspien has stated that:
OK. RE: Map voting. Official rules will be posted when it's ready. That said, we've locked in the rules, etc. and are very happy with where it is now, as it's simple, straight forward, and logical. 1. Your votes are weighted by influence, divided by your total number of votes. So if you vote once, it's worth 100% of your influence. If you vote twice, each vote is worth 50%, etc. The more you vote, the less each vote is worth. 2. Voting will be done in a couple rounds. Round 1 will be all the servers except OCE voting on a pool of 20 maps to determine which 5 maps will be voted on for their server. 3. Round two will be all servers,and will be for each server to decide which map they want of the 5 available. That's it. Simple. At the end of Round 2, each server will know which map will be theirs. Note that round 1 is open results. So you'll be able to see how each map is fairing on each server. Round 2 is closed results, and the results of the vote won't be shown until the round ends. As for people who received a package during searing plague but have no influence, you can vote, but if you truly have 0 influence the vote won't count for much, if anything. Sorry, but that's the way it is. You get to play the game, and have all the benefits of being able to play, but with no influence, your vote doesn't count for much.
There's plenty of questions that can arise from what I just said, but in all cases, the answer should be what you expect. For example: Q. Doesn't that mean people with 10,000 influence are weighted 10x as much as someone with just 1,000 influence? A. Yes.
