Here are some random thoughts on the clue...
10 = ten is a little obvious.So Binary 10 = decimal 2.
Vmax could mean max velocity, again it seems a bit obvious. like stated above it could be the vertical limit.
The Stairway to Heaven idea = Stairs, again obvious. (Or first just doesn't think we know any music). From what I've been told if you play Stairway to Heaven backwards you get a satanic message, so there will be fire & brimstone in this years game.
So in conclusion there will be 2ft high flames that the robots will have to drive through.
Or we can all just wait until tomorrow.
