First of all, there is no greater supporter for CODA and Decipher Trek. However, I am a gamer first and foremost and want to have viable and well-supported games (though a well-written PG and NG are a vital foundation).
Is there any speculation that after the raft of Decipher Trek products coming out are released from the prison known as "the printers," TPTB at Decipher (i.e. Warren Holland) might consider producing a D20 Star Trek rules set utilizing the OGL? I think this would be OK according to the terms of their license with Viacom (parent of Paramount), and would tap into the base of D20-aware gamers for the Star Trek universe (two large bases of population, hmnnn). Decipher need not do much more to support D20 Trek, it could even refer players to the Decipher Trek porducts for sourcebook/game aid reference.
This move wouldn't be unprecedented... SJ Games produced GURPS rules for White Wolf products in the past, and IIRC, they were pretty good. I must admit, the thought of D20 Star Trek is a bit unnerving, but with the writers who brought us LUG Trek and Decipher Trek, it could hardly go wrong.
In addition, I believe Christian, Ross and other from the old LUG vrew were working on a D20 Star Trek after WOTC acquired LUG. I don't know how far along this project was, perhaps Ross could comment?
