I've been happy with using a tertiary fermenter for fruit beers (though they are not really ferementers at that point) to improve taste and clarity. I've had them sitting and settling for as long as a month or so (total, including primary, secondary and tertiary) and been happy with the results. This was with ales, though, not wheat beers. Wheats will always be a bit cloudier anyway, so maybe it is a bit of a toss up how long you want to wait before bottling.
Seldom does waiting do any harm, but if you are feeling antsy, go ahead and bottle it up.
