Will they need to?
We're only going to know that for sure 6-8 weeks after Slim comes out. If it sustains high PS3 numbers (higher than 360 and possibly on par or higher than Wii in Japan) then Microsoft and Nintendo will respond accordingly. Microsoft's response will likely be a price cut and a massive advertising push focusing on 360's new features (coming in the next update) and software.
I wouldn't rule out a NSMB Wii bundle appearing in all major regions in Q4 as part of Nintendo's strategy to create momentum for Wii. I think a Wii pricecut isn't a strong possiblity, but can't be ruled out.
