Let's have a look!
Distance to the goal:
Wii: 6.83 million
Ps3: 5.03 million
X360: 4.29 million
If they all reach the goals at the same time, the marketshare would be as follows
Wii: 42.3%
Ps3: 31.1%
X360: 26.6%
This year, the marketshare has been
Wii: 45.3%
Ps3: 31.2%
X360: 23.3%
Looking at just that, the Wii should reach it first, then the Ps3, then the X360.
