I've just ordered 120 rolls of Neopan Acros, 400 and 1600 to guarantee I can get at least five years' use out of these freshly serviced Leica bodies. They'll only take up the smallest drawer in the freezer. After that...who knows, but if film is still going it'll be a bonus. It's a one-way bet really, since film isn't going to get cheaper over the next five years and it'll keep quite happily at -18 deg C.
