Probably not, because there aren't any concierge rooms in Kidani, so anyone who wants a concierge room will have to be in Jambo.
This is kind of an odd situation, actually - since it's more like SSR opening the Grandstand section than a new resort opening. AKV is already taking reservations - but cannot guarantee that if you request a Kidani room, you'll be able to get one. Does anyone know when they started accepting requests on reservations for rooms in Grandstand before it opened?
Personally, I'd go ahead and book the room and not worry about the building. Then, when the Kidani dates are better defined, I'd call to add that to my reservation. I doubt you'd need to rebook - the points for equivalent level villas are the same for both buildings. It *should* be a request that you can just add to your reservation later - I'd be shocked if you'd need to "rebook" to get a Kidani villa once they start taking requests for them. And since the resort is already open - and all they're doing is opening a new "building" - I doubt owners will have much (if any) advantage to book Kidani beyond the normal 11mo booking window (since you can already book AKV at that date anyway).
I wouldn't be surprised if Kidani was not a guaranteed request for the first year or two, and that they'll only add it as a guaranteed bookable request after a couple of years (like Boardwalk views at BWV and rooms near HH at OKW) - if only to just make things easier for when the building opens.
