Yeah, I totally see that to the extent production has already started on a P90DL. So, I agree with you. The (perhaps irrationally optimistic) question is this: assuming there are finite "units of available factory production" over the next six months, how will those units of production be allocated among new builds and existing retro fits. My understanding is that there are no P90Ds currently in factory production (though many have been ordered). Tesla has to slot the retro fits in there somewhere - I have hard time believing that Tesla will build 100% of all P90DLs that are or become ordered before working on the first existing P85D retrofit. If that were true they might never get around to the retrofits, which would suck.
