Okay, time to put some facts.
Current gap between Wii and Ps360 = 5360K.
Weeks left of the year: 30
Total sales pr week needed: Ps360 + 178K
So far this year, Wii has sold 6938K.
Ps3 has sold 3838K
X360 has sold 2880K.
Ps360 has sold 6718K.
Wii has sold 220K more than Ps360, or an average of 10K more pr week. At that rate, it would take 10 years to make it, but of course, the rate won't stay.
Last 2 months (9 weeks):
Wii: 3859K
Ps3: 1882K
X360: 1477K.
Ps360: 3359.
Wii outsold Ps360 by 500K, or about 55K/week. By this rate it would outsell Ps360 by FY '10.
Last month (5 weeks):
Wii: 2409K
Ps3: 1162K
360: 902K
Ps360: 2064K.
Difference: 345K. Weekly; 69K/week.
By this rate it would make it within christmas '09.
PS: Holiday seasons will not make that big an effect, as the total sales difference isn't super-majorly increased, but of course, it flaws.
For Wii to outsell Ps360 by 178K/week, it would have to break even in Others (sell as much as ps360) (it is currently selling 35K less/week.)
In Japan it would have to increase to 80K/week (it is selling 45K/week more currently, but here holiday should give a major boost, as Ps360 doesn't sell a lot)
In America it would have to sell 90K more /week, compared to 10K/week so far this year. During the last 2 months, it has sold about 60K/week more, and with holiday it could make 80K/week.
This means, that for Wii to outsell Ps360, it would need to average:
Japan: 110K
Others: 200K
America: 250K
WW: 560K/week. Or 2426K/month.
The above estimation includes holiday seasons, but has perhaps not taken it into big enough account. Real number might be closer to 2600K/month.
