I’ll be happy with anything that isn’t Italy, Florida, or London.
I’d love to see Bond return to Russia as a main location, and a return to Japan is long overdue. The southern hemisphere hasn’t been explored at all. I can think of lots of cool things to do with Argentina, South Africa, and Australasia. Ireland would make a fun second-act detour.
If Bond finds himself in the US, he should visit a tribal casino. That would be an interesting variation on the formula.
