You wont get an email. The I got this because I specifically asked them when they didnt update their site with the new date.
I ordered from GAME but it turns out that the company uses a second party for digital downloads called Metaboli; And more over this seems to be the same company being used all over the UK for digital downloads as they are all giving away SH 3 with purchase. Anyhow here's my return email.
Thank you for contacting the Metaboli customer service
