Though Bill does not speak plainly, it appears he suggests that we shouldn't assume any particular robot design. He further hints not to make any large purchases of any particular material. There is a strong possibility that the game will be released sometime in January....
In other words, it may be much ado about nothing (the "inch or two" view) or we may be thrown for a doozy of a different game (the "how can robots move" view). I'm going for the latter.
