The one thing that concerns me, and it has been confirmed, is the heavy solar flares expected about then. Heck, they are already showing up. Not the end of the world, but quite possibly the end as we now know it. They are saying there's a very good chance it could knock out all comunications. Look at what happened in Canada just a few years ago. It took them 6 years to get back on track and they are still not 100% there.
