Yeah, I don't think so either, looks more like an MM style pickup or something. Those Jazzbuckers are a perfect fit for my corvette.
Any word when bestbassgear.com will start distributing them?
Yeah, the Delano DJC 4 HEs won't fit in a jazz routing. They are twin jazz pickups and can be used to replace the twin jazz bridge pickups in some Warwick models like the Infinity. I have a custom 5 string with a pair of them (custom order as they don't normally even make a neck version of that pickup) and I'm very impressed.
But essentially all those pickups are is a pair of Delano's JC 4 HE/M2 pickups wired together. And the JC 4 HE/M2s are awesome as well. Side by side split coils in a blade design. They are exactly what you are describing - very round, humbucking J pickups that have a J meets P sound. Best Bass Gear has sets of them in stock and I think you'd really dig them.
