Hurm dont think the file is that big. I got my copy this afternoon, left it for install for maybe around 30 minutes and can play already, Unifi 5mb user, dont think 4gb download would finish in 30 minutes. But I always check and let the launcher update if there is any before the game release. Also check prior to starting the game there is no background download whatsoever.

Edit : I installed using the disc via setup menu of course

Yes this is what happen to me as well. No big download whatsoever after using the disc to install the game, 30 minutes finished.

Another thing to note is that did you guys update the original game before this. Wings of Liberty had a big update recently 4-5gb if not mistaken, maybe bigger. Problem with the update is that it doesnt show on your progress screen like the optimization update, its kind of hidden and you guys need to check it from the download option instead. So what most people did is that when the progress bar shows the optimization update is complete they closed the launcher because did not notice this. I myself only found about this after reading here in this forum.
