Look at the Wii price cut - initially, while it moved a little hardware, it was nothing stellar. Then NSMBWii came out. So I'd say it's a combination, but price without the accompanying software won't work well, software is more important. You can also see it all year long for the Wii - when there's software, sales are better, when there's none, sales are less. Compare Wii Year to Year. Some periods this year Wii did less well than last year even though the price is lower (no software), some periods it did better (presence of software).
