I just noticed that the KOP Technical Resources page has placeholders for downloads of Labview/C++/Utilities/Driver Station updates. All of those are listed as Coming 1/3/2013 encrypted until 1/5/2015. So in theory you can get those downloaded ahead of time in case the servers are inundated on kickoff day…
Also the Getting started with the 2013 Robot Control system documentation is up, with screenshots of the driver station changes, etc… nothing too revealing about the new game that i can tell…
