Diablo III expansion Reaper of Souls is scheduled to start pre-loading to game clients "this month if all goes well," reveals a Blizzard community manager. It's more-or-less an automated process and needs little input. In fact the pre-expansion patch (2.0.1) will actually contain "all of the expansion data" from the game disc, however expansion-only content won't be playable until March 25th.
