That puts you in the very last group to re-register. I was in the first group to re-register in 2010, and my second re-registration is now coming due. So probably somewhere around 1/12 of the airplanes will be re-registering for the second time this year (assuming normal distribution of registrations, of which I have no idea if that is actually true).

When I did my initial re-registration, it changed the expiration date of my registration to something closer to the time I re-registered. It will be interesting to see what happens to it this time around. Although, based on the earlier link, it seems like it will probably remain the same.
