I think for part of your question (why do they specifically say a week), the length isn't all that meaningful. As in, if they want to more time to make a decision, they'll just announce another week's delay. They have weekly status update conferences, and just cancelling those conferences might be more of a PR risk than just keeping the conference and announcing that they're delaying making a decision.
