We still have to finish our sticky threads with our FAQ/Q&A (Frequently Asked Questions / Questions and Answers) thread. But the answer is simple:
The devs do not give any form of release date or estimnate for any patch, not untill it's officially announced on their website a few weeks in advance.
The reason: It's very hard to set a release date and only at the last moment can they be sure when to release it. And even then it's a though struggle to actually release on the given date. It's just very difficult to estimat how much time it will take to complete an object, let alone a map and then we aren't even talking about fine tuning, which takes weeks.
For your own safety I have locked this thread since the "release date" quetion gets the FH fanbase mob out who will try to hunt you down. Sorry.
But I hope this answers your question.
