Wii Sports Resort did not change what the Wii offers. Since to most consumers it is more of the same and if I wanted a Wii for Wii Sports Resort I also wanted a Wii for Wii Sports then I picked up a Wii already. WiiM+ just does what most people believe the Wii does already. That is the flaw of WiiM+ people were already sold 1:1 by Nintendo even though the Wii doesnt do 1:1.
Hardware sales will likely not increase until a price cut. I suspect that no particular title will boost Wii sales signifigantly since the install base is so high in Japan. Software can sell systems if the software brings in a demographic not already purchasing the system (WiiFit and fitness titles case in point).
Its libraries that sell systems not a single game.
