I just pre-ordered at the Alpha level, and I noticed that the game already has files available for download, even for the versions of the game with release dates in the future. (i.e. all of them, as of the time of this writing) Based on the file sizes, I'm guessing these are just copies of the demo version, as a placeholder for the future. So that I don't waste a bunch of gigabytes of bandwidth downloading the same file five times, can you please confirm for me whether I've understood correctly?
