The most intriguing of which is the notion that Microsoft may be planning a November price cut for Xbox:
Since Microsoft can rely on awesome software rather than dealing with a hardware launch, it has the upper hand right now. If fact, if Nintendo was in this position we'd be seeing a price drop to combat the new systems. Microsoft isn't stupid. I personally expect a drop of up to $100 ($50 is more likely, but Microsoft will be going for a TKO at Christmas) for each bundle starting mid-November.
The general sense seems to be that the Wii will launch under $200, perhaps as low as $149.
