I ordered the Ultimate collection from the SE store (Digital River). At about 3am I got all the codes and music but no download link for the game.

According to the Japanese version of the SoA site (as translated by google) the software is available on March 27. As I write this the 27th is still about 30 minutes away in Japan. Since SE has decided to use DR for it's store I am assuming that DR takes it's directions from the Mother Company and will not release the software until the 27th Japanese time. So in half an hour I will be spamming the refresh button for my email and hope that the download link comes sooner then later.
