For those of you who happen to not to be familiar with CUUSOO, it is a place where anyone could post his or her LEGO set idea. And if that idea will get 10.000 supporters, The Lego Group might release that idea as a real set!
They will not do bigger ships. GlenBricker in his blog wrote an article about why it would not be efficient.
Also, as you can see, the end format of the set is three mini ships.
It's so awesome.
It's still in review stage. I cannot guarantee that it will eventuallybecome an official set.
