Actually, XIV didn't go into actual production till around 2007, when they pulled the XI crew to focus on it. This is why WoTG expansion took over 3 years for them to finish it. Zilart, CoP and ToAU didn't take 3 years for them to finish, even the conclusion mission between Zilart and CoP (Apocalypse Neigh) came out fairly quickly.

The technical demo was just that, a technical demo or we'd have a PS3 version of FFVII if we're using tech demos as a basis on when something goes into production.
