I agree that the devs should keep folks informed, but I also don't begrudge them taking some time to regroup and assess their situation after the whirlwind Kickstarter campaign. I'm sure they're already working on things and I think they'll be served pretty well by taking the past few days to come up with a plan not only for development but also how they plan on approaching the updates as a well-structured holistic part of the project.
Right not they are probably going over the financial's and putting out a formal budget. There is also the matter of any contracts that need to be done with the people and services that will be hired due to the high funding. I know people are wanting updates but if you've ever been on software projects the first few weeks are all meetings and posting updates that say "We had a budget meeting today followed up by some outline meetings, and we even had a meeting to schedule more meetings for tomorrow" will not make you all happy.
I do not expect any real product updates for a few months because until then most of the work will be base code and system coding with no real results for a while.
Just give them some time to get things going.
