There are a lot of unsuperable logical problems with the doctrine of resurrection anyway. The painful apologies of this belief in the NT (e.g. Jesus against the Sadducees in Mark 12//, or Paul against the Corinthian spiritualists in 1 Corinthians 15) do little more than toning down the "physical" aspects of resurrection to avoid the most obvious problems ("they are like the angels in heaven," in the Synoptics; "spiritual bodies" in Paul), but as a result the "resurrection" they present is hard to distinguish from mere soul survival.
Belief in soul survival doesn't imply belief in (bodily) resurrection. It can dispense with it altogether. On the other hand, belief in resurrection does imply belief in something which is to be resurrected -- something more that the material body which comes back to dust.
The Sadducees consistently denied both soul survival and resurrection. The Pharisees consistently accepted both. JWs blend the Sadducean denial of soul survival with the Pharisee's belief in resurrection into a modern concept of objective memories + recreation (whence the technical analogies of voice and image recording, and more recently DNA "codes"). It is definitely not a "scriptural" view, but it can work on the shallowest technical minds.
The Sadducees were mostly impopular aristocrats. The Pharisees were mostly popular laymen. This sociological aspect is still valid. A religion won't be popular if it doesn't offer individual hope in the face of death. Past a certain level of education such a "hope" becomes very difficult to accept.
