I've said it before, and I will say it again. Take as long as you need to, we can all wait for this awesome content. It's the fact that you are still giving regular updates that really shows you are doing the most and the best you can. And I will be the broken record and say you should still take time for yourself and don't over work :P
with this update, we now really know how much you have been working on for this next bit, and how much content it entails. So it makes more sense that you take longer to hammer it all out and properly flesh it out before just throwing it to us to then have it all break and fall apart... rather have less bugs to report, yknow?
