I think that's probably true that having instancing would often times be of greater value for complex models than 64-bit-ness.

However, the way it works out for practical development is the 64-bit conversion involves the most work and upheaval in the code base and it tends to be best to do those kinds of major structural changes right at the beginning of a new version cycle.
