I don't think it works like that, if a thing is out of stock and has demand, then demand goes somewhere else. Of course, there are exceptions, but Kid Icarus does not look like that game people will wait to get eventually - hope I'm wrong, though
I think it's not possible to rent video games in Japan, so the used market is of bigger importance. Games are bought, played through and sold back to a store within a week, so it is kinda like renting, albeit in a bit weird sense.
If a game sells out, more often than not new shipments only arrive when used copies are already plentiful, so games that were initially underestimated ultimately lose out on potential sales.
The exception to this rule are naturally those games that people hold on, therefore not enough used copies get into circulation to satisfy the demand which means that people have to buy new.
