IIRC, the case of conviction w/o a body occurred because the perp confessed. I heard about the case you speak of on FoxNews a week or so ago in an interview with a Dutch lawyer. The suspect in Natalee's case certainly is not going to confess.
I don't recall how long it was exactly the Peterson was walking around after killing Lacy.. but 62 days seems to ring a bell. However, cold, land-locked SF Bay is entirely different from warm, tropical Aruba. A body will degrade much quicker in 80 degree water than it will in 60 degree water; the ocean off Aruba gets really deep really quick; and there is much more marine life in tropical waters than there is in SF Bay - meaning that the remains have most likely been eaten.
As to the jailed suspect, the law there allows them to keep a person in jail almost indefinitely if there is a flight risk, while the investigation is ongoing.
