anyone know when is without a trace coming out on DVD boxset?

i carn't wait as its so good. i want to watch it all in order unlike the few random episodes they show on channel 4

it was first broadcast in the states in sept 2002. CSI season 3 started at the same time and that has a dvd release date.

what is taking them so long to release without a trace as they have almost finished airing season 2 in the states.
