Notch has announced that Mojang has decided to target Nov 11 as the release date for Minecraft. That won't mean much except that it will shift from Beta status and it might go up in price.
Quoting from 11/11/11 : The Word of Notch
the version we deem as the “full version” won’t be very different at all from what the game was like a week ago, and we’ll keep adding features after the release as well, so it’s really more of a milestone when we finally get rid of the Beta label, and some kind of goal for us to work towards. The plan is to be open with this and try to get people to cheer us on as much as possible, but to be open with the fact that the game won’t change much at the actual release day. (It’s more a progress up until that point)
And yes, it will be Remembrance Day in many countries.
