NDPS Vista Client

Does anyone know if there are plans to add NDPS support to the Vista
Client before it becomes a full production client? We are a NW 6.5 shop
who is just now finally killing Queue based printing in favor of NDPS ...
we do not currently have the user training nor the infastructure to go
full on iPrinting at the moment. Preasure from the top is pushing a Vista
rollout sooner than I would like. No NDPS printing support is an absolute
show stopper and may force management to look at ending our
Novell/Microsoft blended network in favor of an all MS One ... YIPES!
