Pet Sports is going to be bundled with the Wii.
It's expanding the market even further.
NES, PS1 and Wii all expanded the market heavily, but they were restricted to 1 race - humans.
Now, Ubisoft launches their animal collection, making animals buy the Wii.
The potential market just became a lot bigger.
