For Dark Souls 3, it looks like the vast majority of that was done at full price as well, with the sales numbers stabilizing at about 950,000 copies before the Steam sale started: http://steamspy.com/app/374320
Dark Souls 1 has an LTD of 2.6 million copies while Dark Souls 2 + Scholars has an LTD of 1.8 million copies, though those have both been very cheap. Dark Souls 3 seems on track to have the largest LTD.
As GhostTrick points out, Metal Gear Solid V has now also passed 1 million copies: http://steamspy.com/app/287700
