I will confirm that Moebius will be at NNL East. I've been in touch with Dave Metzner and they will have a two table display. He hasn't shared any secrets with me, but I don't believe the kits will be available at the show. A little bird tells me they'll be on open water at that time.
Revell will also be at the show with a three table display. Ed Sexton will attend.
We also had Round 2 coming, but sadly John Greczula emailed on Thursday that they regret that the logistics won't work for them this year.
Sad because this would have been the first year we would have had all three major manufacturers in the house!
Generally the manufacturers don't sell kits, they just do corporate displays and talk to folks.
