I guess it is possible that this last-minute price-cut could happen. I won't rely on it, though, and I wouldn't suggest anyone else to do so either. And, yes, part of my point is that we're still getting a "free" game with the system -- what other "next-gen" system comes with a bundled game?
I don't mind that the Remote needs batteries, because you can just get rechargeable batteries, and I'm sure Nintendo, or some third party, will make a rechargeable battery pack and dock that will function well (and mesh smoothly with the look/feel of the system). I'm sure the batteries will be a standard size (presumably AA), which means you can go out to a battery store or a bulk goods store and stock up on all the batteries you'll need for your Wii, probably for about the price of an additional Nunchuk or Remote or both. And that amount of batteris can probably even cover multiple Remotes, once the batteries they probably come packed with wear out.
The price isn't that bad, even though it's not ideal. This means I still need to save over $200 for my Wii (stupid costs of owning a car...) in two months, if I'm even here at launch date. I may be in army boot camp then, which means I'll have to wait until sometime after I'm done with boot camp to get my Wii.
