I just noticed it, but Wii sales userbase are added by .1 percent weekly

[Magera]

for a 50% market this year, it means the Wii will need to sell 175K more units then the PS3 and 360 combined for the next 29 weeks.

BUT, at it's current rate, Yes, it should see a 47% market share in about 3-4 months. (Aprox 17 weeks over 4 months).

It's been shown that the wii can easily make up between 50K and 100K ontop of the combined sales of PS3 and 360 every week WW (Averaged out).
