So apparently the "preload" for the campaign just downloads the MP version for no particular reason, and the actual campaign files will not even begin to download until the game releases. I thought something was fishy when it only wanted to DL something like 30GB, but this is straight up retarded. From what I'm reading it's a WW release (equivalent to 12/8 13:00 EST) so no setting your region to NZ and playing downloading in ~5 hours from now either.
Also:
Biggest takeaway from the DF console review is quality vs. performance mode isn't what you might expect -- quality is actually 4K60 and performance is 1440p120. Those are just targets of course, actual resolution will vary in order to [try to] maintain the desired fps. So most people will want to just leave it on quality mode. Even if you have a 120Hz TV it doesn't seem worth it to play the game at 120 fps while having to deal with the resolution dropping below 1080p at times.
