Hi Joe:
We just recently finished a major expansion project that revamped our original main gallery, added two permanent exhibit galleries and one traveling exhibit gallery. I believe the plan for completely redoing the permanent galleries is 10 years or more, but we're talking about 20,000+ square feet of gallery space and thousands of artifacts, so it's a very large undertaking. We have everything from cars to the dinosaur skeletons up there! Getting the exhibit furniture in and the artifacts installed took over a year on the last go around. Before the expansion, the staff would add/switch certain exhibit components and artifacts out every few years and I'm sure that will happen on some sort of scale with the new galleries, but it will be awhile before we completely redesign the galleries again.
In the 15 months we've been reopened, we've had two shows through the traveling exhibit gallery. We also have four large hallway cases that will be changed out every few years. So even though our main galleries won't be revamped for awhile, we do have the traveling exhibit gallery and our hallways cases that change out regularly.
I think it strikes a bit of a balance. I hope you find something that works well for you!
