According to these links, Microsoft will be putting a price drop on the Xbox 360 that would put the Core setup to $50 less than the Wii, the Premium to only $50 more, and the Elite to $150 more.
It's debatable as to whether or not this would affect sales to casual gamers, but I'm sure it would affect sales significantly anyway. I know I'd pick up either a Premium or Core console at those prices.
It's unconfirmed thus far, but still, it'll be very interesting to see where it goes.
