They may as well refilm "All Good Things..." too!
I know it would never happen, but it would be really cool and unique if they did get the gang back together to film the "future" scenes now that the actors are the correct ages. It would be completely unprecedented and I'm sure it would get a ton of publicity in the news.
Except no one wants to see a sixty year old Data.
Why not? The series established that Data is programmed to age in appearance.
