If this is all based on the fact that the recent games aren't matching the sales curve of NSMBWii then I think I might have to go bang my head against a wall.
NSMBWii was the perfect game at the perfect time. It was the first 2D Mario game on a Nintendo home console in nearly two decades, released when the Wii was still close to its peak, and it coincided with the first official price cut the console received, all of which combined to drive record breaking sales for the year end period.
A game launching outside of a holiday period, on a handheld that still hasn't hit its peak, and a game launching with a console would never, ever be able to match that performance.
NSMBU has a 59% attach rate by VGC numbers, or a 66% attach rate by Nintendo shipment numbers. That's without any bundling, and I'd say that's pretty impressive. If you're going to respond by saying it's an anomaly helped by a low userbase, then I'd ask you why doesn't the Vita, which also has a low userbase, have anything with an attach rate higher than 21%?
I'd honestly say, it seems like instead of doing the usual thing of analysing the data to help you come to a conclusion, you've come to a conclusion and then tried to make the data fit.
