I know they are not 64-bit right now, maybe the next version will be. It just seems weird to me that they are designing Tiger to be 64-bit and I would think they would try to make some of their programs that way too. I know they will function in Tiger either way, that's not what I am worried about. I suppose you are right that they would change the high-end apps first, the ones that would take advantage of it the most.
