Maybe if the "rare" ships sell super well they'll re-up and do extra ships.
Do we have a confirmed master list yet?
Only for #1-30: http://www.startrek-starships.com/eng/ship-order.html
And they certainly will "re-up and do extra ships" if they hit whatever their sales targets are. That's the way their Marvel figurines collection
worked - they announced a block of issues, and then announced an "extension" periodically - and it hit #200, plus
20 "Specials", seven oversized-figurine "Mega-Specials", four double-packs and a few variants/exclusives.
