Well, I have heard that the Weeks Sabre Tempest won't fly - SHAME, SHAME, SHAME! If that's wrong and it does, then IMHO it should spend at least a season flying in the UK in fornt of an appreciative UK audience.
Personally, I'm looking forward to the TFC Beaufighter...
Against all probability? The HP-42. I believe there is a team whose goals is to achive an HP-42 replica, may they succeed.
PS. Well Done England! Yaaaaaayyyyyy!
