If anyone has this on PC you can unlock this early by using a VPN service and connecting to a country like Hong Kong which had the release date down as 26th September @ 4pm BST.
For VPN I currently use TunnelBear as they have a free service of 500MB a month (1GB if you tweet them).
Just turned the VPN on then logged into Origin. As soon as FIFA17 was launched I turned the VPN off.
Job done!
