Longbow Research's James Hardiman believes that the Wii U has achieved just 1.2 software attach ratio in the US.
This means that for every console sold consumers bought an average of 1.2 games. Another way of looking at it is that only one in five Wii U buyers bought an additional game to compliment Nintendo Land.
He says the cause is twofold. Firstly, the inclusion of Nintendo Land in the Premium bundle is compelling enough to stop consumers paying out for a second game. And secondly, the high price of the console themselves left consumers with little wriggle room to find extra cash for additional games purchases.
The numbers compare badly to the console's UK week one attach ratio of two-to-one, as exclusively revealed by MCV last week.
