Motion Controls and succesful games using them can't really be separated as distinct reasons for Wii's success, price OTOH is a distinct reason from them, although not the sole one. But for new users, EVERY Wii game, old or new, is actually new and appealing too, if it's a good one, so, when sales start declining, a lower price could be effective, increasing the potential user base. A great game launch, though, is important too, as the most important games make retailers give the console more shelf space and visibility, so, again, to maximize success, a synergy of all factors is necessary.
