I can't speak for the main developer's, but I am packaging programs that are requested, those that I want/need, and some that are in the 32-bit repos that will likely be requested at some time. The only ones that won't eventually make it to 64-bit are those that are no longer relevant or won't build with newer libraries. Neal and the rest of the developer's may decide to make a release before all packages have been transferred. That is up to them to decide and/or announce. I hope this helps.
