As was said yesterday on the official forum:
Hi,
Just a quick note to let everyone know we are working towards making Elite: Dangerous 1.0 available for download at midday GMT tomorrow (16.12.14).
Thank you so much to everyone who supported us, participated in the early access, and made tomorrow’s release possible.
See you out there, Commanders.
