Members of Motorola's Owner User Groups who have a Droid X are getting invitations to participate in a new and (cough) confidential project. While the invitation doesn't come right out and say it, when you sign up you get a little more information about a May 2011 soak (a fancy term for beta testing), and everyone seems pretty sure it's going to be Gingerbread. This would make sense, as we're under the impression that Gingerbread is ready to go, and we've been expecting it the past few Fridays.
If this project follows along with the timeline of previous projects, expect some sort of OS update in about a week. If we're lucky, expect it to be Gingerbread.
