Upon reaching 1000 support Cuusoo did their "official" review of license availability and declared:
We've looked into the possibility of producing a set based on this licensed property (Star Trek), and since another company has the construction toy license for this IP, we can’t pursue this further as a potential LEGO set. We're sorry to be the bearers of this disappointing news.
In addition to this project, all other Star Trek projects have also been archived.
It appears Cuusoo has been cleaning house. Low support level Jurassic Park and Doctor Who projects have floating around on Cuusoo for quite some time, but it appears they have been removed as well. There is a Dalek project floating around but Daleks have always had some strange IP issues.
This is the eventual fate of Transformers and to some extent Smurfs. Neither of these properties have breached even 300 support though so it will be a long time coming.
