But let's imagine the PS3 drops price, and then advertises a graphic-intensive PS3 sports. What happens then? What happens when the 360 drops price and offers Halo 3? At least Halo 3 is a system seller. Halo 2 sold 8 million copies, and apparently, about half the 360's owners didn't own the original Xbox. What happens when all those people jump on board. Yes, I see what you're saying, that the Wii has something no one else has now, but the PS3 could get it soon, and the 360 also has a heavy hitting, fastest-sellling-game-ever powerhouse coming along too. That's something the Wii can never have. Now imagine the 360 drops to either $250 or $200. The Wii now has motion controls over the 360, but it no longer has price, nor does it have something that is the sequel to the fastest selling game, does it?
Haven't we learned from the Playstation and the Xbox that if you cut your competitors some slack, they will take it and use it to surpass you? Didn't Nintendo lose out in the first place from being too confident? Then last generation, how did the Xbox surpass the Gamecube? There had to be mistakes there, right? So isn't possible that Nintendo's competition is fierce, and is looking for any way to surpass Nintendo's sales and success?
Regardless, a price drop isn't going to hurt Nintendo. They aren't going to lose money off of the Wii any time soon. If they can encourage and already hemorrhaging Microsoft to lose more money by forcing them to drop price, which could eventually drive MS out of the industry, shouldn't they do it? Isn't that a smart decision? Wouldn't we say the same thing about Sony? It wouldn't be illegal to do so, because Nintendo wouldn't even be losing money on each Wii sold.
Regardless, I think that if MS drops the 360's price, Nintendo should wait a week, gather up sales numbers of that week quickly, and if supplies outnumber demands for the Wii, Nintendo should follow suit the week after, so they don't lose any ground. You have to remember this isn't a game, and Nintendo has lost from a similar position they've been in before. Of course, you also have to wonder whether or not Nintendo is out to make a huge profit or if it is out to make a huge profit. If they don't care about the numbers of consoles sold, then they might not want to lower prices, either, that just depends.
Also, remember that Nintendo originally wanted to offer the Wii at a price under $250, and that retailers pressured them into something higher, so that the retailers could actually make something off of system sales. That screams that the Wii has the ability to have the price dropped just a bit, too, and Nintendo wouldn't mind, so long as it was done for good reason.
