Why all this discussion might be, in at least in one sense, moot:

I "decided" not to order PDK on eventual trade in. Would have to wait at least a year for it to appear on order forms, then a year after that to assimilate the reviews. Might be like PCCB when they first came out: they were not so great in their first years.

So for we who are thinking about buying another 997 and want to wait "cautiously" for PDK..., the wait will be at least two to three years.
