Gmail Open to Public?

It seems tha Gmail may finally be opening to the public very soon. They originally predicted the beta period to end last autumn, but it has remained invitation-only well into this year. A few weeks ago members received 50 invites each, to allow more people to join the decreasingly exclusive club. When Gmail was announced last April I signed up to receive news of updates; today I got an email from the team inviting me to open an account. There doesn’t seem to be a signup mechanism on the site yet, but the signs are pointing to an iminent opening.
