I'm with Franko on this one... Wikipedia is fun, but it's hardly a source of Truth. While I'd accept it on trivial matters - anything the least bit controversial is likely to be complete Horse Squeeze.
Natami should stay. The prototypes have been seen by enough people to serve of proof of their existence. As for relevence, there are lots of things on there less relevent... Like the scads of pages regarding the fictional techonolgy and back story of the various sci fi shows. ;-)
